Course Description:

The course is about the main simulation methods of power electronic systems. The simulation is divided into three stages: device simulation, equipment simulation and system simulation. Even for the same device or equipment, different models are applied for different simulation stages. Detailed device models, subcircuit models, state average method, discrete average method, switch mode power supply, SVC and some other popularized models, methods and systems are introduced.
