A novel digital control algorithm for a single-phase boost power factor correction (PFC) converter with fast dynamic response is presented. Based on the converter circuit structure, the track of the output voltage and the inductor current of next switching cycle is estimated in advance. The self-adjusting voltage control loop is adopted to improve the static and dynamic voltage regulation. Meanwhile, the current control loop is implemented only by the estimated output voltage and inductordoi:10.1587/elex.11.20140493 fatcat:7neglxh2ebgubf4x7sfymchlbi
