Abstract: A multi-loop control strategy is proposed based on OCC (One Cycle Control)-controlled Buck-Boost LED lighting driver,and a novel efficient Buck-Boost LED lighting driver is obtained.The multi-loop control strategy principles are analyzed in detail,the system model is built and the control system performance is made in-depth studies.It can be seen through system simulations that the novel multi-loop control system has better performance such as high power factor,low output impedance and good dynamic performance,and it has achieved the desired goal.

Key words: LED lighting, Buck-Boost, multi-loop control, small signal model, power factor
