PSIM program for the design and simulation of power electronics and motor control devices. Power electronics simulation in PSIM enables high simulation speed while delivering high-quality results at the system level.
Verification and modeling in PSIM
The design verification process early in the design process is critical to ensuring a reliable product design. PSIM provides a wide range of design verification tools:
Monte-Carlo Analysis. This is a statistical analysis that calculates the response of a circuit when the parameters of the components are varied randomly according to a specified statistical distribution (eg, normal (Gaussian) distribution, uniform distribution, etc.). Monte Carlo analysis can be used to evaluate the impact of changes in key components on the power converter output. A change in a component may be the result of a manufacturing tolerance or wear of the component over time. Monte Carlo analysis is recommended to understand what tolerances key components should have.
Sensitivity Analysis allows you to determine how the output characteristics of a circuit change when one or more of its components change. This analysis is often used to determine the most sensitive key components in a circuit.
Fault Analysis allows you to analyze the performance of a circuit under fault conditions, such as a short circuit or open circuit of a component. Failure analysis helps evaluate whether a design can pass various failure tests and whether a particular failure could lead to catastrophic consequences.
The results of design verification can greatly help the engineer evaluate and improve the performance and reliability of a design.
Generating embedded code
SimCoder automatically generates high quality C code from the PSIM control circuit. Automatic code generation eliminates human error and allows you to increase design speed, reduce development costs and speed up the release of the finished device to the market.
Thermal modeling
For switching devices (diodes, MOSFETs, IGBTs), thermal modeling allows losses to be calculated either under a fixed temperature effect or when heat is dissipated through a heat sink thermal equivalent circuit. Thermal analysis will ensure that devices remain in a safe working area. Starting with PSIM 11, the user can simulate the characteristics of wide bandgap semiconductors - SiC and GaN - using a MOSFET (Eon).
PSIM core and winding losses for inductors are based on core dimensions, physical structure of the winding, etc. to account for complex relationships such as proximity effects. Loss calculations depend on temperature, and models use junction temperature or core temperature to reflect this dependence.

Batteries, Photovoltaics, Wind Generators
Energy storage and generation are becoming increasingly important as the grid becomes more distributed and renewables make up a larger share of electricity production. Users of PSIM solutions use battery and photovoltaic (PV) models for microgrids, satellite power flow modeling, electric vehicle (EV) drives, and more. All machine models have 4 quadrants, allowing you to "move" or "generate". Use this feature to simulate an electric vehicle propulsion system with drive cycles and regenerative braking, or combine it with our wind turbine model to simulate a wind energy system.
The main characteristics of the model include:
• Various battery models: lookup table based, equation based, variable charge/discharge resistance, etc.
• Various photovoltaic models: based on technical data, normalized based on standards.
