Abstract: A solid-state transformer (10) that maintains output voltage continuity during maintenance is provided. The solid-state transformer includes an input end (101), a plurality of power units (U1 to UM), and an output end (102). The input end is configured to input first three-phase alternating-current electrical power. The plurality of power units are connected in parallel to the input end and the output end, and each power unit is configured to convert the first three-phase alternating-current electrical power into first direct-current electrical power, and output the first direct-current electrical power from the output end. A power supply system (100) including the foregoing solid-state transformer is further included.

Abstract: A power conversion system includes a first controller, a system output end, at least one system input end, at least one power conversion component, and a bus communication apparatus coupled between each power conversion component and the first controller. Each system input end is in a one-to-one correspondence with each power conversion component. Each power conversion component is configured to convert an alternating current input through a first input end of each power conversion component into a direct current, and output the direct current through an output end of each power conversion component.
