With the widespread use of PMBLDCM（permanent magnet brushless direct current motor）, high-power, high-capacity drive technology is one of its research direction. The parallel operation of drivers can effectively expand the drive system’s capacity, but the way is easy to introduce the circulate current. In order to restrain the circulate current, the system including separate direct current power supply for two paralleled inverters that feed the PMBLDCM was analyzed and the character of the system’s circulate current was inferred. The control structure based on the circulate current feedback was put forward. The control structure only needs to control one inverter. Simulation results represent that the control structure can make two direct current supplies that have different amplitudes feed the load, and suppress the circulate current, which achieves a separate power supply brushless direct current motor with drivers in parallel.
