Abstract :
Application of One-cycle Control (OCC) technique for power factor control in three phase boost rectifiers has been successful. This includes operation with one phase of the converter clamped reducing switching losses. It features great simplicity, high performance, and excellent stability. In addition, the Hybrid PWM (HPWM) technique establishes a simple algebraic approach to generate Discontinuous PWM, DPWM, resulting in phase clamping. In previous works Clamping OCC is based on low pass filters (LPF) and utilizes a multiplexer circuit to clamp the phase currents. This paper combines the simplicity of both methods, introducing an OCC clamping technique with the help of the HPWM technique. Moreover, the proposed OCC technique utilizes a lead-lag compensator instead of conventional LPF as well as an input resistance controller to improve dynamic response. It also establishes a relationship between the proposed technique and a hysteresis current controller with clamping technique. Simulation and DSP based experimental results confirm the proposed approach.
