When the power is connected and S1 is pushed, 220V voltage will be sent to AC contactor KM’s coil, and make KM connected. Then C begins to charge. When S1 is released, C’s charging current makes KM remain connected, and VD will be connected to KM by S1 S2. Then the alternating current power will charge C in positive half period while discharge C in negative half period. KM will remain connected.
