Electronic device, power supply circuit and control circuit thereof

Abstract

The application provides an electronic device, a power supply circuit and a control circuit thereof. The power supply circuit comprises a power factor correction circuit, a DC bus, an inverter circuit, a voltage conversion circuit, a bidirectional rectifier circuit and a battery. The first end of the power factor correction circuit receives an input voltage, the second end is connected to the inverter circuit through the DC bus, and the third end is connected to the battery through the voltage conversion circuit and the bidirectional rectifier circuit in sequence. The battery in the power supply circuit provided by the application can reuse part of the circuit such as the power factor correction circuit during charging and discharging, so that the structural complexity of the power supply circuit and the electronic device thereof is reduced.
