High-voltage interlocking control circuit of fuel cell air compressor

The utility model relates to a fuel cell air compressor high-voltage interlocking control circuit which comprises a BMS (battery management system), an air compressor controller and a motor end high-voltage alternating-current connector, and the air compressor controller comprises a low-voltage connector, a high-voltage direct-current connector, a motor current sensor and a controller end high-voltage alternating-current connector. The motor current sensor is connected between the motor power supply and the motor-end high-voltage alternating-current connector; an HVIL signal source in the BMS is connected back to the HVIL signal detection device in the BMS through the first low-voltage connector, the high-voltage direct-current connector, the controller-end high-voltage alternating-current connector and the second low-voltage connector in sequence, and the controller-end high-voltage alternating-current connector is connected with the motor-end high-voltage alternating-current connector in an inserted mode.
