Abstract
The voltage conversion circuit includes a first direct-current conversion circuit connected to an electric load, a secondary transformer coil connected to the first direct-current conversion circuit, and a primary transformer coil coupled to the secondary transformer coil. The primary transformer coil is configured to generate, based on an initial voltage inputted to the primary transformer coil, an electromagnetic field and couple the electromagnetic field to the secondary transformer coil. The secondary transformer coil is configured to generate an induced current by virtue of the electromagnetic field, generate a secondary output voltage based on the induced current, and transmit the secondary output voltage to the first direct-current conversion circuit. The first direct-current conversion circuit is configured to adjust, based on a predetermined demand voltage of the electric load, the secondary output voltage to obtain a target voltage.
