Orcad PSpice
enterpriseSPICE circuit simulator used for power supply and converter design.
Cadence-oriented Orcad integration that preserves a SPICE-first schematic-to-sim workflow for power electronics designs.
Orcad PSpice is a SPICE-based simulation environment used in power electronics design workflows for circuit-level switching, transient behavior, and model-led device characterization. It supports SPICE netlist driven runs, mixed-signal co-simulation workflows, and model execution paths tuned for power circuits that depend on parasitics and component-level detail.
PSpice is also used alongside Cadence toolchains, where engineers can move schematics and models into a consistent simulation flow when they already standardize on Cadence verification tooling. Compared with Saber, NI Multisim, and Typhoon HIL, it carries a stronger emphasis on SPICE netlist workflows and simulator control, while it offers less built-in real-time and hardware deployment depth for closed-loop HIL than dedicated HIL and co-simulation stacks.

GeckoCIRCUITS
vertical specialistPower electronics circuit simulator with integrated thermal modeling.
Reusable behavioral device and power stage model packages that carry parasitics through switching transient studies.
GeckoCIRCUITS is geared toward converter engineers who need to simulate switching behavior with enough circuit detail to carry parasitics into performance metrics like losses, voltage stress, and dynamic response. Model reuse matters because power electronics studies depend on repeated re-simulation of the same device and layout assumptions under different control settings. The workflow aligns with mixed analog system design tasks that often start in averaged reasoning and then move into circuit-accurate transient investigation for boundary conditions.
A tradeoff appears in the depth of hardware-in-the-loop integration, since GeckoCIRCUITS is better positioned for design-time simulation than for real-time closed-loop execution. A common usage situation is iterating SiC MOSFET characterization assumptions and switching waveforms while keeping controller parameters fixed, then switching the sweep dimension to PWM timing or modulation amplitude to isolate sensitivities.

How to Choose the Right Power Electronics Simulation Software
For power electronics simulation software, the real separator is how faithfully it reproduces your switching behavior and how easily you can set up studies from a repeatable workflow, not just which analysis names it offers. Look at switching analysis accuracy and solver transparency before anything else.
Switching waveform accuracy and loss trends
Why it matters
If switching analysis accuracy is weak, gate timing, node waveforms, and derived losses can drift even when the circuit runs. You’ll waste time reconciling results instead of iterating designs.
How to check
Run the same circuit twice using different time-step controls (or solver settings) and compare key waveforms like inductor current and device voltage. Check whether switching loss trends and RMS values stay consistent across runs.
Power device model library coverage
Why it matters
Device model coverage matters because power electronics simulation depends on parameterized behavior, not just topology. Missing or incomplete models force awkward workarounds.
How to check
Ask for a demo or sample that includes the device type you use (e.g., MOSFET or IGBT) and confirm it supports the controls you need (e.g., gate charge, temperature dependence). Compare the required parameter list to what you can realistically source.
Gate drive and controller interaction modeling
Why it matters
Many real errors come from how the drive and control signals interact with switching events. If controller interaction is shallow, results won’t match hardware behavior.
How to check
Provide or load a test setup where the drive includes realistic delays (e.g., turn-on/off timing) and verify the simulator reproduces the expected switching transitions. Ask whether the drive signals can be imported from a typical modulator or control waveform workflow.
Solver options and convergence transparency
Why it matters
Solver transparency helps you trust long runs and troubleshoot when they fail. Without visibility, you can’t tell whether discrepancies come from physics or numerics.
How to check
Inspect what the tool reports during simulation: step size behavior, warnings, and any convergence notes. Run a case that needs tight switching resolution and check whether you can adjust settings and get interpretable feedback.
Automation for repeatable parametric studies
Why it matters
Automation for repeatable studies keeps iteration honest when you sweep duty cycle, load, or device parameters. Manual setup leads to inconsistent comparisons.
How to check
Set up one parametric sweep on a demo (e.g., load step or control parameter change) and confirm it can run unattended. Check whether results are output in a consistent structure you can reuse across experiments.
Postprocessing metrics and data export control
Why it matters
Good postprocessing metrics turn waveforms into decision-ready numbers like RMS current and averaged electrical quantities. Data export control reduces rework when you compare runs.
How to check
Look for built-in plots and calculated metrics relevant to switching converters, then verify you can export raw signals and computed metrics with consistent naming. Recreate a simple metric (e.g., average output current over a window) and check it matches the tool’s reported value.
Red flags
- Waveforms change significantly when you adjust basic time-step controls
- Device models require parameters you cannot realistically obtain or verify
- Simulation output hides convergence issues instead of reporting what to tune
Fit by situation
- If you regularly compare loss numbers between design revisions, prioritize switching waveform accuracy and loss trends.
- If your circuit behavior depends on realistic turn-on/turn-off timing, prioritize gate drive and controller interaction modeling.
- If you run many sweeps for design space exploration, prioritize automation for repeatable parametric studies.
