Design of a Novel Voltage Supply Applied for Measure System of High Voltage Side in Power System

Abstract

A current/voltage supply is presented based on the technology of PWM. It adopts GTR as the shunt. It can convert the current supply that is generated by 220 v alternating voltage to a voltage supply with low heat rate and stable output voltage. This power supply is especially adapted to be used as the power supply for measure system of a high voltage side in power system. The operating principle of the circuit and the pivotal technology are analyzed, and the simulating and experimental results are also given in this paper.
