Research of a Programmable DC Power Supply and its Novel Protection Circuit

Abstract

In this paper, a DC power supply and its novel protection circuit are presented. The proposed new DC power supply is consisted of the output voltage control circuit, driving circuit and the overcurrent protection circuit. The structure and principle of every part about the power supply have been detailed. From a large number of experiments and measurements, it is testified that the lowest electronic noise, high stability, self-protecting, programmable and user-configurable are all merits of the proposed DC power supply.
