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.

Discontinuous conduction mode (DCM) and continuous conduction mode (CCM) in the boost PFC rectifier design for constant frequency operation are usually focused in separate considering distinct controllers and respective trade offs. This paper proposes a named hybrid one-cycle control (HOOC) that presents a smooth mode transition inside one mains half-cycle. One-cycle control (OCC) technique presents advantages such as operation with unity PF, large signal stability, noise immunity, low cost and simplicity. The proposed strategy allows operation in a large power range.
