The invention provides a power supply system provided with a distributed low-power power supply module. The system comprises a high-voltage power box which outputs a first DC power supply; the train wiring is connected with the high-voltage power box and provides a first direct-current power supply; wherein the air conditioner direct-current power supplies are formed by connecting a first number of small-power power supply modules in parallel and are configured to the corresponding direct-current variable-frequency air conditioning units in a distributed mode, and the small-power power supplymodules are used for converting the first direct-current power supply into a second direct-current power supply so as to drive the direct-current variable-frequency air conditioning units; and the auxiliary inverter is composed of a charger and a second number of low-power power supply modules connected in parallel, the auxiliary inverter is connected with the high-voltage power supply box, the low-power power supply modules are used for converting the first direct-current power supply into a second direct-current power supply, and the charger is used for outputting a third direct-current power supply. The system is relatively high in overall efficiency, relatively low in cost, relatively small in weight and size, low in wiring difficulty and high in stability.
