- A zero-voltage and zero-current switching electroplating power supply is developed,which has realized ZVS for the leading leg and ZCS for the lagging leg. 研制了零电压零电流开关电镀电源,其超前臂实现了零电压开关,滞后臂实现了零电流开关。
- A current mode zero-voltage and zero-current switching (ZVZCS) inverter TIG welding machine is developed in this paper,which realizes ZVS for the leading leg and ZCS for the lagging leg. 研制了电流模式零电压零电流开关TIG焊机,其超前臂实现了零电压开关,滞后臂实现了零电流开关。
- Fortunately, this defect can be overcome in the FB-ZVZCS-PWM converter, which the freewheeling current can be attenuated to zero and maintained so that the lagging leg can realize ZCS. 采用FB-ZVZCS-PWM变换器可克服这一问题,它在超前臂关断后,将原边环流电流衰减到零并保持,使滞后臂实现零电流开关。
