摘要: Embodiments of the present disclosure disclose a power supply conversion circuit and a power supply conversion method, capable of improving efficiency of a power supply conversion. The power supply conversion circuit includes a primary transformer coil, a secondary transformer coil, and a first direct-current conversion circuit. The primary transformer coil is coupled to the secondary transformer coil; the secondary transformer coil is connected to the first direct-current conversion circuit; and the first direct-current conversion circuit is connected to an electric load. 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.

摘要: 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.
