Zusammenfassung:The invention relates to a passenger train power supply device, in particular to a passenger train direct-current power supply device, which solves the problems of output current oscillation, large required filter inductance, large required capacitor size and large required capacitor weight of an existing four-quadrant rectification train direct-current power supply device based on an IGBT device.The passenger train direct-current power supply device comprises a transformer, a four-quadrant rectifier based on an IGBT device and a BUCK chopper, wherein the four-quadrant rectifier takes electricity from one secondary side of the transformer, a direct-current output end of the four-quadrant rectifier is connected with an input end of the BUCK chopper, and an output end of the BUCK chopper serves as the output of the passenger train direct-current power supply device; and a switching device S1 in the BUCK chopper adopts a SiC device. According to the passenger train direct-current power supply device, the main ci
