Abstract

This chapter shows how power electronics circuits, electric motors, and drives, can be simulated with modern simulation programs. The main focus will be on PSpice®, which is one of the most widely used general-purpose simulation programs and Simplorer®, which is more specialized towards the power electronics and motor drives application area. The first example of a power electronics circuit is a step-down converter with synchronous rectification. For the purpose of synchronous rectification, the diode, which connects the inductor to ground in the regular circuit, is replaced with a power MOSFET transistor. To achieve this, the lower MOSFET must be turned on whenever the upper MOSFET is turned offand the current in the inductor is positive. If the current in the inductor is continuous, the drive signal for the lower MOSFET is simply the inverted drive signal for the upper MOSFET. The Q input of the induction machine would correspond to the armature winding input of the DC machine and again both inputs would receive DC current.
