ZVZCS三电平弧焊电源控制电路的研究
ZVZCS Three-level control circuit of arc welding power source
ZVZCS逆变电源的控制系统采用移相控制，这是一种恒频调脉宽控制方案，它能实现功率开关管的零电压和零电流开关。针对这种控制方式，Unitrode公司推出了UC3875集成芯片 。本课题采用的UC3875芯片是整个逆变器控制电路的核心。本文主要对UC3875进行了一些介绍，讲述了它的工作原理和功能，并对控制电路的参数进行了设计计算。
ZVZCS inverter control system uses phase-shift control, which is a constant frequency pulse-width adjustment control program that enables the power switch of the zero-voltage and zero-current switching. In view of this control method, Unitrode Corporation introduced the UC3875 integrated chip. The topics used UC3875 chip inverter control circuit of the entire core. In this paper, carried out some of the UC3875 presentation about its working principle and function, and control circuit design and calculation parameters.
