Hybrid one-cycle control technique for three-phase power factor control

One-cycle control technique has been a prominent and suitable solution for improving power quality with the help of three-phase rectifiers. This study proposes a generalised control strategy for the three-phase power factor rectifier based on both the one-cycle control technique and the hybrid pulse-width modulation (PWM) strategy. Improvement of the performance while providing very low-current total harmonic distortion (THD) is achieved with the proposed scheme. Discontinuous and/or continuous PWM operation is possible with advantages of simplicity, robustness, and low cost. Simulation and experimental results confirm the feasibility of the proposed controller.
