A three-phase six-switch pulse width modulation (PWM) rectifier based on one cycle control is researched. The control laws of three-phase six-switch PWM rectifier are deduced. A new PFC controller based on one cycle control technology is designed. Its control logic is very simple and the multipliers and input voltage sensors are not needed. Its control(More)
A four-quadrant DC/AC converter for wind power flow optimization system is designed. Firstly, the basic idea of wind power flow optimization and control is analyzed. Secondly, working principle of the four-quadrant DC/AC converter is explained and its linear small signal mathematical model in the rotating reference frame is constructed. Then, based on the(More)
One cycle control technology is a novel non-linear control technology without multiplier. It has the function of modulation and control at the same time. A new general PWM modulator for single-phase power factor correction with one cycle control is proposed in this paper. On the basis of analyzing one cycle controlled traditional single-phase Boost power(More)
