Abstract
In direct torque control system of brushless DC motor,the voltage vector is often defined as zero voltage vector while all power switches are off. This definition is simple,but cause big torque ripple. A new zero voltage vector was presented. The influence of zero voltage vector on torque in dynamic state and generated state was analyzed. That the new zero voltage vector which has lower steady-state torque ripple was pointed out,and could conveniently realize four quadrant operation of the motor. The simulation results verify the validity of the theory analysis.关键词
