高功率因数零开关逆变式电焊机

High power-factor zero-switching inverter weld er

提出了一种新型的单级高功率因数零开关逆变式电焊机主电路拓扑方案,该焊机的逆变器采用零开关技术,且同时完成功率因数校正功能,仿真试验证实了其良好的效果。

A novel high power factor zero-switching inverter welder topology is presented,which compounds PFC with PS-ZVSCS-PWM Inverter Bridge in a single-stage.The simulations and experiments of the prototype verify the good effects.
