Simulation-Based Design of Electric Drive Systems
9.1 Introduction
In Chapter 8, we discussed some of the circuitry that is used in electric machine drive systems. At the heart of every drive system lies a power electronic circuit whose operation is closely controlled by a control system. The power electronic circuit works in unison with the control system to feed the terminals of the machine.
Proper operation of a drive depends chiefly on how suitably the power electronic circuit and its control system are designed and tuned. For example, in an ac–dc–ac converter system (see Example 8.4), the quality of the output voltage and current, as well as the dynamic response of the system, partially depends on the size of the dc storage elements ...
