ZCS

The decreasing time of free-wheeling current is relative to duty cycle in the exiting FB-ZVZCS-PWM soft-switching inverter arc welding power supply with the block capacitor, and it is hard to achieve zero current switching ( ZCS) for lagging leg with low duty cycle.

现有FB-ZVZCS-PWM软开关弧焊逆变电源采用阻断电容衰减原边环流电流所需的时间与占空比有关，占空比很小（电源输出电压很低）时滞后臂难以实现零电流开关。
