Disclosed in the embodiments of the present application is a power conversion circuit, comprising a direct current conversion circuit, a pulse width control circuit, and a transformer. The transformer comprises a primary transformer coil and a secondary transformer coil. The direct current conversion circuit is connected to the primary transformer coil, and is used for adjusting an initial voltage inputted to the direct current conversion circuit to a target voltage. The pulse width control circuit is connected to the primary transformer coil, and is used for generating a pulse square wave on the basis of the target voltage. The primary transformer coil is coupled with the secondary transformer coil. The primary transformer coil is used for generating an electromagnetic filed according to the pulse square wave, and coupling the electromagnetic field to the secondary transformer coil so that the secondary transformer coil generates an output voltage.
