Abstract:
    The motor driver includes the DC power supply, the filter consisting of two serial-connected split type capacitors and the 1st and 2nd bridge arms of converter consisting respectively of two serial-connected switch transistors. The A phase winding of the motor connects to the serial-connected point of two switch transistors of the 1st bridge arm via a current transducer. The B phase winding of the motor connects to the serial-connected point of two switch transistors of the 2nd bridge arm via another current transducer. The C phase winding of the motor connects to the serial-connected point of two capacitors. Omitting two power transistors, the driver raises the reliability of the motor driving system, simplifies the control means, reduces the cost and realizes the system miniaturization.
