A three phase half controlled bridge circuit with constant current and high efficiency is designed in the charged loop of the welding power supply. So a limiting current resistance is canceled.
在焊接电源的充电回路中设计了三相桥式半控、恒流高效充电回路，取消了限流电阻；

Under different conditions, property of controlledcurrent is different. This shows that the influence of resistance value is different for property of controlledcurrent of control element and load.
