Abstract
The present application relates to a voltage driving circuit and system and a household appliance. The voltage driving circuit includes a diode; a thin film capacitor; a resonant circuit configured to be connected to a three-phase power supply and enter a non-resonant operating state in a case where a working current of a load is greater than a present current; a rectifier circuit, of which an input end is connected with the resonant circuit; a switch device, of which a first end is connected with a first output end of the rectifier circuit and an anode of the diode, a second end is connected with a second output end of the rectifier circuit and a first end of the thin film capacitor, wherein a cathode of the diode is connected with a second end of the thin film capacitor; an inverter circuit connected with the first end of the thin film capacitor and the second end of the thin film capacitor, and configured to be connected to the load; and a control device, connected with a control end of the switch device, the resonant circuit, and the inverter circuit.
