Power electronics systems are nonlinear variable structure systems. They involve passive components such as resistors, capacitors, and inductors, semiconductor switches such as thyristors and MOSFETs, and circuits for control.

The analysis and design of such systems presents significant challenges. Fortunately, increased availability of powerful computer and simulation programs makes the analysis/design process much easier.

PSIM^(R) is an electronic circuit simulation software package, designed specifically for use in power electronics and motor drive simulations but can be used to simulate any electronic circuit. With fast simulation speed and user friendly interface, PSIM provides a powerful simulation environment to meed the user simulation and development needs.

This book shows how to simulate the power electronics circuits in PSIM environment. The prerequisite for this book is a first course on power electronics. This book is composed of eight chapters:

Chapter 1 is an introduction to PSIM.

Chapter 2 shows the fundamentals of circuit simulation with PSIM.

Chapter 3 introduces the Simview^(TM). Simview is PSIM's waveform display and post-processing program.

Chapter 4 introduces the most commonly used components of PSIM.

Chapter 5 shows how PSIM can be used for analysis of power electronics circuits. 45 examples are studied in this chapter.

Chapter 6 shows how you can simulate motors and mechanical loads in PSIM.

Chapter 7 introduces the SimCoupler^(TM). Simcoupler fuses PSIM with Simulink^(R) by providing an interface for co-simulation.

Chapter 8 introduces the SmartCtrl^(R). SmartCtrl is a controller design software specifically geared towards power electronics applications.
