Abstract
The power supply conversion circuit includes an isolation transformer, and the isolation transformer includes at least two primary coils and at least one secondary coil. Each primary coil is connected to a half-bridge circuit by using a first resonant network, and half-bridge circuits corresponding to the at least two primary coils are connected in series between two electrodes of a power supply. The half-bridge circuit is connected in parallel to a voltage divider, the voltage divider includes a first capacitor and a second capacitor that are connected in series, a first terminal of the first resonant network is connected to an intermediate node of the half-bridge circuit, and a second terminal of the first resonant network is connected to a connection point between the first capacitor and the second capacitor.
