Saber
enterpriseMixed-technology simulator for power electronics and automotive electrical systems.
Electrothermal coupling tied to power switching simulation enables junction temperature estimation inside the same transient run.
Saber is used to simulate converters and drives where switching transients, parasitics, and control interactions must be resolved in the same run. The tool supports electrothermal coupling for junction temperature estimation, which matters for SiC MOSFET characterization and SiC device operating-point validation. It also supports SPICE netlist import so existing transistor-level or component-level work can be reused inside a larger system simulation.
A key tradeoff is solver and model fidelity sensitivity when mixing very small time steps with highly nonlinear wide-bandgap device models. Saber is a strong fit for teams that already have device models and parasitic extraction outputs and need repeatable system-level runs across controller iterations.

- +SPICE netlist import reuses transistor-level work
- +Averaged and detailed switch modeling supports fidelity tradeoffs
- +VHDL-AMS style co-simulation supports controller-plant linkage

NI Multisim
enterpriseSPICE simulation environment with power electronics component libraries.
SPICE netlist import into a schematic workflow reduces rebuild time when leveraging existing power stage models.
NI Multisim is a schematic-centric SPICE environment where power converter topologies can be assembled from standard components and then validated through transient waveforms and AC small-signal runs. It supports SPICE netlist import for reusing existing circuit descriptions, which helps when parts of a model originate in different toolchains. Device characterization work and control-loop iteration can stay connected to the same schematic model, which reduces translation overhead between design and test cases.
A practical tradeoff is that detailed semiconductor switching physics and electrothermal coupling depth depend heavily on the available device models and the level of abstraction used in the circuit. Teams often use Multisim when they need fast iteration on switching waveforms, averaged switching approximations, or state-space oriented control assumptions rather than fully physics-resolved wide-bandgap behavior. It fits best when solver stability and waveform probing matter more than deep custom model authoring.
- +GUI-first schematic workflow for converter building and signal probing
- +SPICE netlist import supports reuse of existing circuit descriptions
- +Transient and small-signal AC analysis from the same model
- +Parameter sweeps speed up control tuning without rewriting schematics

The environment supports importing SPICE netlists and assembling plant models into a real-time execution graph suitable for running against controller implementations. For research teams, it also supports co-simulation paths for mixed analog and behavioral blocks to validate control design choices before hardware deployment.
A common tradeoff is that real-time constraints can force stricter solver settings and model simplifications than many offline SPICE runs. HIL scenarios work best when the controller has a defined sampling time step and the plant model includes the required IO interfaces for the hardware target. Tight integration is especially useful for IEC 61850 workflows in grid and protection test benches where plant responses must be synchronized to controller timing.

How to Choose the Right power electronics simulation software
This buyer's guide covers power electronics simulation software tools for switching loss analysis, switching transients, electrothermal junction temperature estimation, and controller validation workflows. It references Saber, NI Multisim, Typhoon HIL, PSIM, Simulink, Opal-RT, PowerSim, PLECS, EMTP, and LTspice.
The guide explains what each tool is best at and how to pick the right fidelity and execution mode for the workflow. It focuses on integration depth, automation hooks, and governance over model and solver behavior where those capabilities are part of the tool’s execution path.
Power electronics simulation tools for switching, control, and electrothermal verification
Power electronics simulation software models converter circuits and controller behavior to study switching transients, switching loss, and device-level stress in time-domain runs. Many tools also support thermal coupling for junction temperature estimation or connect plant models to controller execution.
Teams use these tools to iterate on converter topology, gate drive timing, controller sampling behavior, and protection events without rebuilding hardware for every parameter sweep. Saber and PSIM illustrate two common practice styles, where Saber emphasizes electrothermal coupling inside the same transient run and PSIM emphasizes fast averaged and switching device checks in one circuit build.
Evaluation criteria that map to real power-electronics workflows
Selecting power electronics simulation software is mostly about controlling fidelity and execution mode while keeping model reuse friction low. Teams usually choose based on how well device parasitics and switching events are represented and how easily controller integration and automation runs are executed.
The criteria below focus on concrete capabilities such as electrothermal coupling inside switching runs, deterministic real-time deployment for controller timing, and model reuse via SPICE netlist import across both circuit and block-diagram workflows. The tool names in each criterion point to where those capabilities appear most directly.
Electrothermal coupling that runs inside the power switching transient
Saber ties electrothermal coupling to power switching simulation so junction temperature estimation can happen inside a single transient run. PowerSim also connects device loss evaluation to junction temperature estimation, which fits projects that need thermal outputs derived from the same switching behavior.
SPICE netlist import with schematic or diagram reuse
NI Multisim reduces rebuild time when existing SPICE netlists are imported into a schematic workflow for transient and small-signal AC analysis. Typhoon HIL, PLECS, and EMTP also use SPICE netlist import to reuse power stage models instead of re-creating device networks by hand.
Switching fidelity controls that span averaged and detailed behaviors
PSIM supports both averaged and switch-level transient behavior in one circuit build, which supports switching-loss checks and waveform verification without changing tools. PLECS uses averaged switch modeling with a switching-level option so the same model can toggle between speed and transient fidelity when the investigation needs more detail.
Deterministic real-time execution for controller hardware-in-the-loop
Typhoon HIL synchronizes converter dynamics with controller timing through real-time hardware-in-the-loop plant execution. Opal-RT provides a deterministic real-time deployment flow with a time-step aware simulation pipeline for controller hardware-in-the-loop and controller-in-the-loop setups.
Controller and plant co-simulation with automation-friendly test harnesses
Simulink supports automated test harnesses and scenario-based runs so controller variants can be exercised across operating points with consistent timing. Saber also supports controller-plant linkage through VHDL-AMS style co-simulation workflows when the design requires closed-loop verification.
Measurement-driven transient scripting for switching event analysis
LTspice includes directive-driven measurement and waveform scripting for capturing switching losses and recovery intervals during transient runs. This fits workflows where gate drive and switching event timing are iterated with repeatable measurement directives rather than building larger controller test harnesses.
Pick by execution mode first, then choose fidelity and automation depth
A practical selection starts by deciding whether the work needs offline switching transients or synchronized controller execution. Typhoon HIL and Opal-RT target real-time controller validation, while NI Multisim, PSIM, Saber, PLECS, EMTP, and LTspice focus on offline circuit simulation with analysis and scripting.
After execution mode is chosen, fidelity and integration depth decide the tool. Saber and PowerSim prioritize electrothermal junction estimation inside switching workflows, while NI Multisim and PLECS emphasize SPICE netlist reuse and fast iteration for converter control validation and tuning.
Choose the execution shape: offline transient analysis or real-time controller synchronization
Select Typhoon HIL when converter dynamics must stay synchronized with controller sampling in a hardware-in-the-loop loop. Select Opal-RT when deterministic real-time deployment is needed for controller hardware-in-the-loop with time-step aware execution.
Select fidelity targets: averaged for iteration or switch-level for switching-loss and protection events
Select PSIM when averaged and switch-level transient behavior must coexist to run fast switching-loss and waveform verification checks in one circuit build. Select PLECS when a single model must toggle between averaged switch modeling for speed and switching-level fidelity for deeper transient inspection.
Verify thermal requirements: junction temperature estimation inside the transient run or post-processing
Select Saber when junction temperature estimation must be tied to the same transient switching run through electrothermal coupling. Select PowerSim when the workflow explicitly connects device loss evaluation to junction temperature estimation for converter stress and thermal performance studies.
Optimize model reuse and workflow speed: SPICE netlist import into your preferred build style
Select NI Multisim when a schematic-first workflow should import SPICE netlists and then support transient and small-signal AC analysis on the same model. Select PLECS or EMTP when block-diagram or EMTP-style circuit projects should reuse SPICE netlists for switching-device time-domain studies and scripted parameter sweeps.
Plan integration and automation scope: test harness automation versus external co-simulation setup
Select Simulink when repeatable parameter sweeps and scenario-based test harnesses must exercise controller variants with consistent timing in the same modeling environment. Select Saber or Typhoon HIL when co-simulation style controller-plant linkage is required, but note that Typhoon HIL also requires attention to solver convergence and controller IO interface wiring for custom controller integration.
Pick the measurement workflow: scripted transient directives versus scenario-based automation
Select LTspice when switching-loss and recovery intervals are captured with directive-driven measurements and waveform scripting in transient runs. Select Simulink when automated test harnesses and parameter sweeps are central to exploring controller variants across operating points without manual plot-by-plot iteration.
Who should use each power electronics simulation tool
Different power electronics teams need different execution modes and fidelity targets. The best-fit recommendations below map directly to each tool’s stated best_for and standout workflows.
The guide emphasizes offline switching and electrothermal verification for design iteration, and real-time controller synchronization for validation against plant timing. Each segment recommends tools that match the cited workflow shape.
Power teams running switching transients plus electrothermal junction checks
Saber fits this audience because electrothermal coupling is tied to power switching simulation so junction temperature estimation can happen inside the same transient run. PowerSim fits the same thermal-output objective with built-in electrothermal coupling that connects device loss evaluation to junction temperature estimation for converter designs.
Converter control validation teams that iterate from schematics to transient and AC
NI Multisim fits this audience because SPICE netlist import lands inside a schematic workflow that supports transient analysis and small-signal AC analysis from the same model. This also aligns with fast parameter sweeps for control tuning without rebuilding the schematic for each variant.
Teams validating controllers against plant dynamics with real-time timing alignment
Typhoon HIL fits this audience because real-time hardware-in-the-loop plant execution synchronizes converter dynamics with controller timing and supports scenario runs for repeatable regression testing. Opal-RT fits teams that need deterministic real-time execution path for controller hardware-in-the-loop with time-step aware simulation pipeline.
Motor drive and converter engineers needing fast averaged studies with optional switch-level fidelity
PSIM fits this audience because it prioritizes fast averaged and switch transient simulation for power stage iterations with controller and power co-simulation workflows. PLECS fits this audience because averaged switch modeling accelerates switching-loss studies while the switching-level option supports deeper transient fidelity when needed.
Protection, grid interaction, and switching transients with SPICE reuse and scripted runs
EMTP fits this audience because it combines average switch behavior with time-step switching events in one simulation run and supports SPICE netlist import plus scripted parameter sweeps. LTspice fits engineers who want fast transient switching studies with built-in measurement directives and waveform scripting for gate drive and recovery intervals.
Common failure modes in power electronics simulation projects
Several recurring pitfalls show up across power electronics simulation tooling because switching models and solver settings interact with thermal coupling, co-simulation, and model reuse. These mistakes lead to unstable simulations, incomplete thermal outputs, or extra integration work that delays iteration.
The fixes below reference which tools handle the situation well and where execution still needs discipline because solver behavior and model fidelity depend on the modeling approach.
Using an EMI-first expectation with tools that focus on circuit switching fidelity
PSIM and PLECS have limited depth for EMI prediction workflows compared with EMI-focused spectral analysis approaches. For EMI-focused investigations, the workflow needs a tool designed for electromagnetic prediction rather than relying on limited spectral coverage.
Assuming junction temperature outputs will be accurate without model fidelity
Saber and PowerSim can provide electrothermal coupling outputs, but wide-bandgap device models depend on external parameter quality. NI Multisim and PLECS also limit electrothermal coupling compared with specialized multiphysics depth, which can reduce thermal accuracy if semiconductor parameters are incomplete.
Running highly nonlinear switching transients without solver tolerance tuning
Saber’s highly nonlinear switching behavior can require careful solver tolerance tuning to reach stable convergence. Simulink also becomes hard to stabilize for large power models unless solver and step selection are handled with discipline.
Overlooking real-time performance limits when deploying HIL models
Typhoon HIL real-time execution can require model simplification to meet deterministic timing constraints. Opal-RT also depends on time-step aware execution, so models that are too stiff for the discretization and solver settings can produce convergence issues.
Expecting advanced co-simulation depth without integration effort
Typhoon HIL integration work increases when controller IO interfaces need custom wiring, which adds engineering time beyond the plant model setup. Simulink external co-simulation setup for hardware-in-the-loop scenarios can add integration time when controller and equipment interfaces are not already aligned.
How We Selected and Ranked These Tools
We evaluated Saber, NI Multisim, Typhoon HIL, PSIM, Simulink, Opal-RT, PowerSim, PLECS, EMTP, and LTspice using criteria tied directly to switching transients, electrothermal coupling, co-simulation for controller validation, and automation capabilities. We rated each tool on three areas where the provided product details explicitly show differences: features, ease of use, and value, with features carrying the most weight and ease of use plus value each carrying less weight. This ranking is editorial research based on the described capabilities and workflow fit for power electronics teams, not on hands-on lab testing or private benchmark experiments.
Saber ranks highest because electrothermal coupling is tied directly to power switching simulation, enabling junction temperature estimation inside the same transient run. That capability lifts Saber primarily on features, while its solver-related switching depth and co-simulation pathway for controller-plant linkage support the same end-to-end verification workflow that teams typically want.
