PSIM 

Simulates renewable energy conversion projects, motor drives with digital controls and more. Supports ABC to DQ0 transformation, Low Pass Filter, PID Controllers, etc.

PSIM provides engineers with the tools to perform circuit simulations used in motor drive or power electronics. It comes equipped with various modules, such as Spice, Motor Drive, or Digital Control, and it's mostly used by professionals in research fields.

It has a standard interface, though it's not quite in line with nowadays standards, and has a rich main menu, with a toolbar on top and bottom of the screen, and a left side panel. The buttons and icons have a basic design, and the time response to user commands is sometimes poor.

The modules that the software is equipped with are well-implemented and quite easy to integrate with platforms as JMAG, Modelsim, Simulink, or TI kits. In order to facilitate user interaction PSIM offers in-depth tutorials and Guide manuals.

With the Digital Control feature, users are able to analyze systems in z-domain and convert from analog to digital control. This module flexible allows users to save execution time.

Another interesting module is Renewable Energy. This enables you to simulate, manipulate and analyze a renewable power system with the aid of innovative models for solar, wind and battery storage systems.

Other included modules are SPICE- for SPICE simulation-, Motor Drive-for electronic-based motor systems-, Thermal-for power loss calculations-, and SimCoupler-for co-simulation operations.

In conclusion, PSIM is an important utility for designing circuits and circuits simulations, therefore is best suited for professionals. The cons are the high memory usage, and a slight button delay.
