Control circuit of direct current brushless motor and inverter air conditioner

The utility model discloses a control circuit of a direct current brushless motor and an inverter air conditioner with the control circuit. The control circuit includes an intelligent power module; the intelligent power module comprises an over-current sense terminal and a signal receiving terminal for receiving the drive signals output by a central processor; the control circuit also includes an over-current detection module for over-current detection to the intelligent power module and several and gate logic circuits; each and gate logic circuit has two input terminals and one output terminal, one input terminal is correspondingly connected with the drive signal output terminal of the central processor, the other input terminal is connected with the output terminal of the over-current detection module, and the output terminal of each and gate logic circuit is correspondingly connected with the signal receiving terminal of the intelligent power module. The intelligent power module and the direct current brushless motor are effectively prevented from burning out by over current, and thereby the circuit stability is raised.
