The invention provides a train power supply system. The train power supply system comprises a train power supply (1), a voltage transformation and current transformation device (2), a current commutation device (3) and electric equipment (4) which are arranged sequentially in the current flowing direction, wherein an output end of the voltage transformation and current transformation device (2) is divided into two branches, one branch is connected with the current commutation device (3), the other branch is connected with a direct current module (5), and an output end of the direct current module (5) is connected to a train control device (6). According to the train power supply system, repeated conversion of the power supply can be avoided, a circuit is simple, and the EMC (electro magnetic compatibility) effect is good. The invention further provides a train air-conditioning system using the train power supply system and a control method of train air conditioning.
