I INTRODUCTION

This paper presents an overview of the most the rectifier, different types of voltage
important DC-DC converter topologies. The converters can be made:
main object is to guide the designer in selecting
the topology with its associated power - Step down “Buck” regulator
semiconductor devices.
- Step up “Boost” regulator
The DC-DC converter topologies can be
divided in two major parts, d
