摘要
系统分析了移相全桥软开关换流控制原理,提出了采用饱和电感、隔直电容,充分利用励磁能量实现软开关的电路拓扑。针对CO2焊的特点,使用单片机进行波形控制,从而减少了焊接飞溅,保证焊缝成形美观。
The topic is based on the analysis of the transition rules of the phase shifting full bridge zero voltage switching inverter,and puts forward circuit topology adopting saturable inductor,capability capacitance,and magnetic inductance.For the characteristic of CO 2 welding,the wave of the welding is controlled by microprocessor,which decrease the spatter and get the good performance.
