Powersim - Model PSIM 2022.1 - Ultimate Simulation Environment for Power Conversion and Motor Control

The Design Verification Toolset provides Monte Carlo Analysis, Sensitivity Analysis, and Fault Analysis tools for design verification.

More than 25 years ago, Powersim created its core design and simulation software PSIM to empower engineers in the power electronics design industry. PSIM provides expert circuit and systems-level design and simulation capabilities. Our software has evolved to include multiple products in addition to PSIM plus third-party software integration, and hardware target support.

Design Verification Toolset

Starting the design verification process at an early stage of product development is critical in ensuring a reliable product design.

PSIM provides a set of design verification tools, including Monte Carlo Analysis, Sensitivity Analysis, and Fault Analysis, to assist Design Failure Mode and Effect Analysis (DFMEA) of a power converter design.

These analyses are easy to set up, and the results can greatly help engineers evaluate and improve the performance and reliability of the design.

Embedded Code Generation

Let your code be a self-starter. SimCoder generates high-quality, consistent C code from a PSIM control schematic automatically — free from human error — to boost the speed of your design, reduce your development costs, and propel your innovations to market.

SimCoder generates C code that is ready to run on specified physical hardware for real-time operation. You can see all the supported hardware targets here.

SimCoder’s automatic code generation function seamlessly integrates simulation with hardware implementation and greatly speeds up the development and design process.

If a hardware target is not specified, the C code generated by SimCoder can be inserted into the user’s own code for system control.

C Block Functionality

The C block allows you to enter custom C code directly without compiling the code, unlike in the case of external DLL blocks, where a compiler is needed to compile the code into a DLL. The C block code will be interpreted and executed at runtime by a built-in C interpreter in PSIM.

This block makes it very easy to define any functions for the block through the powerful C programming language and to test your control algorithms in C code implementation.

There are two types of c block:

1. The Simplified C Block for simple functions, which is embedded code generation compatible.
2. The C Block for more advanced functionality, including custom function definition and library inclusion.

Thermal Simulation

For switching devices (diodes, MOSFET, IGBT) the Thermal Module provides loss calculation with either a fixed junction temperature impact or with heat dissipation through a heatsink thermal equivalent circuit, which will allow you to ensure that your devices stay within the safe operating area. Since v11 you can model the device characteristics of wide bandgap — SiC & GaN — with the MOSFET (Eon).

PSIM’s core and winding losses for inductors make use of core dimensions, physical winding structure, etc. to ensure complex relationships like proximity effect are considered.

The loss calculations are thermally dependent and the junction temperature or core temperature is used by the models to reflect this dependence.

The users of PSIM are diverse, spanning all aspects of power electronics, continents & countries, and all sizes of companies from multinational conglomerate to small startups and consultants.

PSIM has been servicing the industry for more than 20 years and our users’ products are everywhere:

• Consumer electronics like air conditioners, washing machines, cars, TVs, and mobile phones
• Industrial products such as pumps for oil & gas, field-winding control for utility generators, drives for conveyors, and renewable energy applications covering PV & battery microgrids or wind power systems.

PSIM has a strong worldwide presence with leading researchers and academic institutions. Many groundbreaking and novel discoveries have been first simulated with PSIM before hardware prototyping has begun.

We are always asking our user base for feedback and for 20 years the feedback is the same. PSIM is fast, robust, accurate, and easy to use.

We at Powersim understand the specific challenges our Industry and Academic users encounter each day: the need to test models and theories quickly yet accurately; the demand for trusted results in the face of time pressures; and the requirement for robust software that’s still easy to use.
