MOTOR DRIVING APPARARATUS AND METHOD FOR CONTROLLLING OF THE SAME

摘要

PURPOSE: A motor driving device and a controlling method thereof are provided to reduce the complexity of a circuit by removing a filter circuit and a power source. CONSTITUTION: A PAM circuit includes a converter. An inverter is serially connected to the PAM circuit. A motor current control unit (600) controls the inverter. A PAM control unit (400) generates a PAM control signal and controls the converter.
