摘要: In this paper, the phase feedforward control (PFFC) for single-phase boost-type switching-mode-rectifier (SMR) is proposed. Compared to the fixed feedforward signal in the conventional feedforward control, the phase of the conventional feedforward signal now is controllable according to the load power which makes PFFC be able to yield more feedforward efforts for high load power. For implementing the high-sampling-frequency function of power factor correction (PFC) in low-cost DSP-based system or in digital integrated circuit, the economical proportional-type (P-type) feedback controller is used in the proposed PFFC instead of using the proportional-plus-integral-type (PI-type) feedback controller or other complicated controllers. In addition, we can use relatively small P-type parameter in the proposed PFFC which also increases the system stability The analysis and design of proposed PFFC are described in detail. The simulation and experimental results also demonstrate the proposed PFFC. Target applications of the proposed PFFC are low-cost digital control for terrestrial 50-60Hz system whose performance is limited by the speed of the digital controller.
