Principle and parameter design of arc welding inverter using soft switching technique

摘要

The soft switching are welding inverter reduces switching losses and improves operating envitonment of devicesby using Zero-Voltage -Transition (ZVT) technique .Step-by-step analysis of each timing interval and the associatingvoltage and current waveforms are included for the Full-Bridge Zero-Voltage-Switched PWM comerter,Numerous designequations supporting the phase-shifted soft switching technique are highlighte .
