The invention relates to an urban rail vehicle auxiliary power supply system, an air conditioning unit and an urban rail vehicle. The auxiliary power supply box comprises: an auxiliary high-voltage box; an auxiliary power supply box, wherein a DC600V power supply device is arranged in the auxiliary power supply box, and comprises a boost circuit of which the input end is connected with the outputend of the auxiliary high-voltage box, and two groups of phase-shift full-bridge circuits of which the input ends are connected with the output end of the boost circuit, the input sides are connectedin series and the output sides are connected in parallel; an auxiliary inversion unit, wherein the input end of the auxiliary inversion unit is connected with the output ends of the phase-shift full-bridge circuits; and a charger unit, wherein the input end of the charger unit is connected with the output ends of the phase-shift full-bridge circuits. A DC600V output voltage system is added, powersupplies with output of DC600V, AC380V and DC110V can be provided for a train, and the air conditioning unit adopts direct input of DC600V, so an intermediate rectification link is omitted, meanwhile,a nonlinear load-air conditioning load is omitted for AC380V power supply of the train, the working efficiency is improved, the weight is light, and energy is saved.

    本发明涉及一种城轨车辆辅助供电系统、空调机组及城轨车辆,辅助供电系统包括:辅助高压箱;辅助电源箱,内部设有:DC600V电源装置,包括输入端与辅助高压箱的输出端连接boost升压电路和输入端与boost升压电路的输出端连接且输入侧串联、输出侧并联的两组移相全桥电路;辅助逆变单元,其输入端与移相全桥电路的输出端连接;充电机单元,其输入端与移相全桥电路的输出端连接。本发明增加DC600V输出电压制式,能够为列车提供输出为DC600V,AC380V和DC110V电源,空调机组采用DC600V直接输入,省去中间整流环节,同时列车AC380V供电省去非线性负载‑空调负载,提升工作效率,重量轻,节省能源。
