The invention discloses an auxiliary alternating current system for an internal combustion motor train unit. The auxiliary alternating current system comprises an auxiliary generator set, a direct current circuit and more than one inverter circuit. The auxiliary generator set supplies power to a cooling fan and a traction ventilator of a corresponding internal combustion motor train unit through the inverter circuit. The auxiliary generator set supplies power to a direct connection load of the corresponding internal combustion motor train unit through the direct current circuit. The auxiliary alternating current system further comprises a train power supply generator set, a first switch module and a second switch module. The train power supply generator set respectively supplies power to an air compressor, a driver air-conditioner, an electric storage unit and a direct current load of the internal combustion motor train unit through the first switch module; the auxiliary generator set respectively supplies power to the air compressor, the driver air-conditioner, the electric storage unit and the direct current load of the internal combustion motor train unit through the second switch module; and the first switch module and the second switch module are in interlocking. The auxiliary alternating current system has the advantages of being simple in structure and high in reliability.
