Quick Power Supply Design
Power supplies are the backbone of the electrified world. Converter requirements, advancements in semiconductor devices, magnetics, topologies, and control techniques require dynamic, accurate, and purpose-built power electronics simulation tools.
PSIM solves today’s power supply designers’ key challenges. PSIM can evaluate multiple topologies and converter operation characteristics, switching speed and its impacts, power loss and efficiency, electromagnetic interference (EMI) filter design and operation, and it can provide control design and implementation all in one intuitive, connected environment.
Comprehensive Motor Drive System Analysis and Design
Users need the industry’s best tools for motor drive design, simulation, and analysis – that’s why PSIM should be any team’s choice to speed up and simplify the motor drive design process.
PSIM helps users overcome the most common challenges that engineers face in the motor drives field, including:
- Motor performance evaluation,
- Controller design of current/speed/torque feedback loops (sensored or sensorless control, FOC/DTC), and
- Power converter sizing and design
Non-Ideal Device and EMI Simulation
Users don’t always need a realistic switch transition for their design work. But voltage/current overshoot, electromagnetic interference (EMI), and other transient interactions can be the difference between a finished product and a prototype that winds up in failure.
Users can utilize PSIM’s non-ideal switch models to understand:
- Voltage/current overshoot
- Conduction EMI
- Gate drive requirements
- Long cable interactions
- Other high-frequency interactions with parasitic inductors and capacitors
The addition of many small L and C values – combined with high-frequency ringing – can cause numerical instability, and users need a robust solve engine like PSIM.

Multi-Level Converters
Modular multi-level converters (MMCs) are becoming more important as the grid grows smarter and renewables play an ever more important role. Simulating them poses unique challenges for power electronics designers because of their diversity. Simple multi-level converters and MMCs can have very few switches while more complex systems can have hundreds. This means teams must carefully consider losses, efficiency, controllability, harmonics, and interactions with other local converters.
With so many aspects to consider, teams can’t spend time waiting around for each simulation to finish – with PSIM, users can handle them efficiently, accurately, and quickly.
EV/HEV Powertrain Systems
Power electronics and motor drives are at the heart of EV/HEV powertrain systems.
With PSIM’s Design Suites, teams can set up and start simulating an HEV powertrain system in no time. This helps system engineers, hardware engineers, and control engineers study the system’s aspects and speed up the development process.
Microgrid and Grid-Connected Design and Simulation
No matter if you call it smart grid, distributed generation, solid-state transformers, or microgrid, these complex systems comprised of multiple power converters, generation sources, distributed loads, and complex control schemes used to be tough to simulate. Not anymore.
With PSIM, users can design multiple converters working together covering many applications, including:
- Photovoltaic microgrids and grid-connected systems with distributed and bidirectional energy storage
- Satellite power systems with PV and battery working to power many different Point-of-Load (POL) converters
- Down hole applications in oil and gas
- Electric drivetrains with bi-directional energy storage and POL converters for planes, trains, and automobiles
