An efficient power factor correction converter is presented. Two boost-topology switching cells are interleaved to minimize EMI while operating at lower switching frequency and soft switching to minimize losses. The result is a system with high conversion efficiency, able to operate in a pulse-width-modulation (PWM) way. Seven transition states of the ZVT converter in one switching period are described. In order to illustrate the operational principle key, implementation details, including simulations, are described. The validity of this converter is guaranteed by the obtained results.

This paper proposed a kind of new control method for resolving the problem of the Direct Torque Control (DTC)'s greater torque pulsation problem at low speed, this method is based on Space Vector Pulse Width Modulation (SVPWM). SVPWM is a kind of excellent Pulse Width Modulation (PWM) scheme. It can not only improve the inverter DC voltage utilization, reduce harmonic losses, restrain torque pulsation, also easily generate high-precision real-time waveform by the high-speed digital signal processor. The simulation results of this system by Matlab/Simulink indicate that the space vector PWM direct torque control can efficiently reduce the pulse of motor torque and flux linkage.
