Abstract: The present disclosure provides a power converter, including: a pre-stage circuit, configured to receive an input voltage and convert the input voltage to a bus voltage; and plurality of post-stage circuits, connected in parallel to an output terminal of the pre-stage circuit, and configured to receive the bus voltage from the pre-stage circuit and each converts the bus voltage to an output voltage. The power converter provided by the present disclosure can effectively solve the problems of isolation and the wide range of operating voltage, and can take both of high efficiency and high power density into consideration.
