21.1 Introduction

Conventional dc power supplies operate at a given dc output voltage into a constant or near constant load. However, pulse loads such as lasers, fiashlamps, railguns, and radar require short but intense bursts of energy. Typically, this energy is stored in a capacitor and then released into the load. The rate at which the capacitor is charged and discharged is called the repetition rate, T, and may vary from 0.01 Hz for large capacitor ...
