| Abstract: | This paper presents a kind of tlyback converter utilizing an active-clamp circuit. This circuit can suppress the high turn-off voltage spike of the switch that is caused by the parasitic oscillation and can achieve ZVS for both switches. This paper analyses the behavior of the ZVS active-clamp flyback operating and practical design considerations. Then Experimental waveforms are given to verify that both switched in the circuit can achieve ZVS and it works stably as the auxiliary power in the motor control system. |
