Introduction

Many automotive and industrial applications require higher voltages than is available on the input power supply rail. A simple DC/DC boost converter suffices when the power levels are in the 10W to 50W range, but if higher power levels are required, the limitations of a straightforward boost converter become quickly apparent. Boost ...
