Overview of DC-to-DC Voltage Conversion

Home | Articles | Forum | Glossary | Books


As electronic devices have become larger and faster, circuits have evolved and ac motor control has become more popular than dc motor control for industrial applications. Today dc-to-dc voltage conversion is more widely used in power supply circuits because every piece of equipment that has an electronic board in it requires a wide variety of dc voltage supplies. Each voltage must be supplied from a power supply. This means that computers, PLCs, and all other electronic equipment require a dc power supply. Today the older chopper circuits have been modified into the new power-supply technology with newer types of circuits and they are all more commonly called converters. Most often one will find converter circuits today in switch-mode power supplies (SMPS).
