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.
