MOTOR CONTROL APPARATUS FOR ALTERNATING FREEWHEELING AND CONTROL METHOD OF ALTERNATING FREEWHEELING FOR MOTOR

摘要

The present invention relates to an apparatus for controlling a motor for alternating freewheeling and a method for controlling alternating freewheeling of a motor. (A, A', B, B') comprising a signal generating unit and an output distribution unit for distributing the signal output from the signal generating unit to each switching element, the A' signal is an inverted signal of the A signal and the B` signal is an inverted signal of the B signal, and the signal generator is configured to have a high freewheeling operation state in which the A signal and the B signal are high, and the A signal and the B` signal are high It is characterized in that the signal is generated in one of a motor-on operation state and a low freewheeling operation state in which the A′ signal and the B′ signal are high.
