The utility model belongs to a special power suitable for on -vehicle electric air conditioner direct current has brush fan, including DC -DC transfer circuit, no. 2 choppers of arbitrary circuit topology, its characterized in that, in the output directness of the DC -DC of any one circuit topology converter and connect no. 2 choppers, 2 air conditioning system's evaporation or condensation fan can be received wantonly to the output of way chopper, 2 the way chopper realizes by its solitary control circuit independent control that 2 group's fans independently carry out timing control separately. The utility model discloses a 2 the speed governing of realization fan that can be very convenient is adjusted to the output duty cycle of way chopper, and 2 the tunnel adjust and do not have the relevance each other, can be separately independent regulation. Whole power is the power sum of 2 groups, and the system can the respective output of the two sets of fans of automatic allocation under the certain circumstance
