摘要:
A power feeding device of a non-contact charging device includes a power factor improvement circuit which converts an AC power supply to DC, and improves a power factor, a smoothing capacitor connected to an output end of the power factor improvement circuit, an inverter circuit which includes a plurality of switching elements, and generates an AC signal using a voltage of the smoothing capacitor as a power supply, a power feeding section which feeds power based on the AC signal to a power receiving device, and a control circuit which modulates at least one of a duty factor or an operation frequency of each of the switching elements of the inverter circuit in synchronization with the AC power supply.
