半桥式逆变焊接电源工作状态分析

Working state analysis of semi-bridge inverter welding power source

半桥式逆变焊接电源的一个完整工作周期分为 6个阶段 ,以 8个时段给出了不同阶段的功率开关管集电极电压、中频变压器一次侧电流和二次侧电压以及整流二极管电流的波形。

The working period of semi bridge inverter power source is distinguished into six stages. The voltage and current waves of devices including intermediate frequency transformer,power switch output rectifiers are given respectively at the eight different time period. The mathematics analysis of current and power transferred in primary side of intermediate frequency transformer is also given.
