PSIM

What Can PSIM Do?

• Calculate losses generated by fast switching of power devices

• Evaluate motor drive efficiency

• Perform EMI (electromagnetic interference) analysis and digital–analog control of signals

• C-language compatible: through the C-block, C code can be executed directly in PSIM during simulation without pre-compilation.

• SPICE link: with SPICE models, parasitic interactions and gate-drive circuits can be analyzed in the PSIM environment.

PSIM Product Capabilities

Fast power converter design
       Power supplies are the backbone of modern electrical society. Whether in semiconductors, magnetic components, power electronic circuits, or control-related technologies, the demand for power converters continues to grow, and therefore a dedicated, accurate, and continuously evolving power electronics simulation tool is needed.

 

√ PSIM Addresses Many Challenges Faced by Today’s Power Electronics Designers:

• Evaluate operating characteristics of various circuits and converters

• Assess switching speed and its corresponding impact

• Analyze switching power losses and efficiency

• Design and analyze EMI filters

Comprehensive motor drive system analysis and design
       For motor drive design, simulation, and analysis, PSIM can help teams streamline the design workflow. PSIM helps users overcome common challenges in the motor drive field, including:

• Motor efficiency calculation
• Controller design for current, speed, or torque feedback (with or without sensors, including FOC/DTC control)
• Planning and design of power electronic converters

 

Non-ideal component and EMI analysis

       If real-world switching transient phenomena such as voltage/current overshoot, electromagnetic interference (EMI), and other transient interactions are ignored during the design stage, discrepancies between the design and actual performance may lead to product failure.

       By using PSIM’s nonlinear switch models, more in-depth analysis can be performed, such as:

• Voltage and current overshoot

• Electromagnetic interference (EMI)

• Gate drive conditions

• Interactions in long transmission lines

• Parasitic inductance and capacitance interactions at high frequencies

       PSIM’s robust solver can handle circuits with multiple parasitic inductances and capacitances under high-frequency conditions without numerical instability.

 

Multi-Level Converters
       With the continuous development of smart grids and renewable energy, modular multilevel converters are receiving increasing attention. However, modular multilevel converters are highly flexible: in some cases a multilevel converter may have only a few switching devices, while in other complex systems it may contain hundreds or even more switches. For power electronics engineers, simulating such systems is a major challenge. The analysis team needs to carefully consider losses, efficiency, controllability, harmonics, and interactions among multiple converters.

       There are many aspects to consider when dealing with multilevel converters. By using PSIM, analysis teams can solve these problems more efficiently, accurately, and quickly.
 

EV/HEV drivetrains
       Power electronics and motor drives are at the core of EV and HEV drivetrains. With the PSIM motor control design suite, teams can rapidly build HEV drivetrain models and start simulation and analysis. PSIM helps system, hardware, and control engineers study all aspects of the system and accelerate the development process.
 

Microgrid and grid-tied design and simulation

       Whether it is smart grids, distributed generation, solid-state transformers, or microgrids, these complex systems include multiple power converters, power sources, distributed loads, and sophisticated control strategies, making simulation very challenging.

       With PSIM, users are no longer limited by application scope and can overcome these difficulties to design converters that meet their requirements, such as:

• Solar microgrid and grid-tied systems with distributed and bidirectional energy storage

• POL converters used in satellite systems with solar power and batteries

• Downhole applications in the oil and gas industry

• Powertrain systems with bidirectional storage and POL converters for aircraft, trains, and automobiles
