Circuit schematics (PSIM Schematics)

PSIM simulator

Waveform display program (Simview)

PSIM Basic can be used for analysis and design of power converter and control systems for a wide variety of applications, including (but not limited to):

AC/DC Rectifiers
Active Filters
Battery Chargers
Grid-Link Operations
Power Factor Correction
Power IC Components and Adjustable Speed Drive Systems
Reactive Power Compensators
Single-Phase and Three-Phase Inverter and UPS Systems
Switchmode Power Supplies

PSIM Basic has a comprehensive library containing numerous electrical engineering items to design power structures, power components and control loops.

PSIM Schematics includes a comprehensive library of electrical engineering items:

Power Circuits: RLC Branches, Switches, Transformers
Control Circuits: Filters, Function Blocks, Logic Elements, Common-Used Elements (PI Block, Multiplexer, Operational Amplifier...)
