Introduction to Power Electronic Converters for Motor Drives
1. Introduction
In this chapter we look at examples of the power converter circuits which are widely used with motor drives, providing either d.c. or a.c. outputs, and working from either a d.c. (battery) supply, or from the conventional (50 or 60 Hz) utility supply. The coverage is not intended to be exhaustive, but rather to highlight the most important features and aspects of behavior which recur in many types of drive converter.
Although there are many different types of converter, all except very low-power ones are based on electronic switching. The need to adopt a switching strategy is emphasized in the first example, where the consequences are explored in some depth. ...
