摘要
全桥相移零压开关逆变焊机将PWM控制与软开关相结合,具有2种控制的优点,有助于焊机向小型化、质量轻、低损耗方向发展。在相移零压开关设计中,使用专用相移芯片,大大简化了焊机控制电路,同时增强了控制功能,改善了焊机的整体性能。
In the full-bridge phase-shifting ZVS welding inverter,the PWM control and the soft-switching are combined together,so it possesses the virtues of two kinds of control and contributes to the welding inverter's development of minimizing,light weight and low cost.In design of full-bridge phase-shifting ZVS welding inverter,the application of special phase-shifting chip simplifies the control circuit,strengthenes control functions for the welding inverter and improves performance of the welding inverter evidently.
