This application provides a solid-state transformer and a bus voltage equalization method for a solid-state transformer. The solid-state transformer may include a plurality of cascaded modules and a bus voltage equalization module. Input terminals of all the cascaded modules are connected in series, and output terminals of all the cascaded modules are connected in parallel, and are used as a parallel output terminal of the solid-state transformer. The bus voltage equalization module is connected in parallel to the parallel output terminal of the solid-state transformer. Each cascaded module may include a bus capacitor (for example, all capacitors connected in series to each other on a direct current bus). The bus voltage equalization module may equalize bus voltages of all the cascaded modules by consuming a part of energy in the bus capacitor in each cascaded module. Based on this application, the bus voltages of all the cascaded modules may be equalized by using the bus voltage equalization module. In this way, there are lower costs and higher applicability.
