| Abstract: | This paper presents a design of the main circuit of the soft-switch DC/DC converter based on full- bridge phase-shifted control for electroplate power supply. The paper analyzes the realization of ZVS in ahead bridge and lagging bridge. At last, a digital control system using TMS320LF2407A as the main control chip is designed to achieve digital control algorithm, as well as ZVS for IGBT. The 24kW/20kHz prototype is also designed. The experimental waveforms show the validity of the control method. |
