PSIM is one of the fastest system-level simulators on the market. This means you can test hypotheses early and easily, and get from design to implementation quickly. PSIM is capable of simulating large and complex power converter and control systems in a short time.


PSIM is used by some of the top universities and companies in the world, and is known for its ability to deliver accurate results without sacrificing simulation speed.


PSIM has an intuitive user interface, easy implementation, and outstanding technical support. You’ll be up and running in no time.


PSIM allows for mixed domain simulation. Design with analog s-domain, digital z-domain, or both in the same simulation.


Experienced SPICE designers have likely encountered the frustration of SPICE model syntax compatibility. PSIM allows users to run LTspice. Leverage PSIM’s dual model definitions which allow one schematic to be used with PSIM or SPICE.

The link between PSIM and SPICE is constantly improving. Starting with PSIM v12 you are able to simulate the frequency response of a switch mode power supply in LTspice or PSIM SPICE without the use of average models. A very similar method to how the native PSIM engine simulates a frequency response. PSIM will handle the heavy lifting of injecting each frequency and compiling the gain and phase response at each frequency.

PSIM can simulate almost anything:


The PSIM AC sweep tool is optimized for the study of switching power converters.

There is no need to generate equations or average models of your topology in order to sweep open loop, loop gain, close loop, input impedance, and output impedance transfer functions. Digital delay can be introduced and the impact observed.


PSIM supports simulations that are setup to generate embedded code for industry standard C2000 MCU’s from Texas Instruments.


With the Modcoupler Modules you can verify your FPGA control code while PSIM simulates the power stage.


PSIM allows users to easily change between ideal devices, detailed switching models, thermal devices, with the release of PSIM V11.0, SPICE models, and with PSIM V11.1 LTspice support. This allows you to choose the appropriate model for your simulation requirements.


PSIM allows you to change parameter values and view voltages/currents during simulation. It’s like having a virtual test bench running on your computer.


PSIM has an extensive library and includes pre-built sample circuits and tutorials to support you in both research and teaching.
