Abstract

A DC power supply of full bridge phase shift pulse-width modulation zero-voltage-switch(FB-PS PWM ZVS) with passive auxiliary network was developed, which is used in magnetic field measurement. From the testing data, the current stability of this power supply is better than ±1×10~(-4) per 8 h.
