One cycle control is a novel nonlinear control technique. Compared with traditional power factor correction [PFC）, PFC using this technique has several advantages in many aspects, such as more simplified control system, faster transient response and better input disturbance rejection. This paper presents a detailed analysis on the principle of single phase PFC employing one cycle control and on the implementation circuit. Furthermore, the single PFC with one cycle control IC was carried out. The simulation and experimental results have proven that one cycle control PFC has flexibility, good performances and low cost for single phase PFC design solution, put forwards propose use take advantage of utilize dedicated.
