Abstract

This chapter addresses the most important type of DC VtoV converter topology that can power LD subsystems. It converts a CVS with one level of voltage into a CVS with another voltage level using an intermediate DC-to-AC voltage converter (called an inverter in the power-electronics literature). Specifically, the topology is a HF switch-mode quasi-resonant converter with a transformer that matches the output and input voltage levels, a ballasting inductor in the inverter, and a capacitive output to reduce the output voltage ripple.
