Chapter 3

Flyback Converter with Voltage-Mode Control

Abstract

The mechanisms of energy transfer employed by the forward converter and those by the flyback converter in this chapter are quite different.

The flyback converter transfers energy sort of indirectly by storing a bucket in one time step then dumping it (to the load) in the other, and the cycle repeats. The storing act is instituted via an inductor.

Along the same coverage sequence, this chapter presents flyback converters with voltage-mode control. In theory, flyback converters can work in two conduction modes, continuous and discontinuous, attributed to the initial current of inductor storage. However, in continuous conduction mode, the issue of right-half-plane zero exists and makes ...
