Abstract：In order to reduce the reactive power, improve power factor and efficiency of permanent magnet induc?tion machine (PMIM), a direct power control (DPC) method is proposed in this paper. After analyzing the active power and reactive power, the mathematical model of PMIM was established based on the rotating coordinate sys?tem. According to the analyzing the power characteristic of different vectors which vectors exist , the vector switch table of the direct power control( DPC) was established. By this method the reactive power can be re?strained around zero. Simulation results show that under the same conditions of active power output, DPC method can effectively reduce the reactive power, improve power factor, to save energy.
