Abstract

This paper presents an integrated-stage ACDC LED driver based on Flyback and Class-E converter with high power factor. The Flyback circuit works in discontinuous conduction mode (DCM) to realize the power factor correction (PFC) function, and the Class-E circuit is used as DC-DC converter to transform the energy to the LED load. The integrated topology can decrease the cost of system. Moreover, the Class-E converter provides soft switching operation in resonant mode, which can improve the converter efficiency. The active switch is operated with constant duty radio and pulse frequency modulation (PFM). A 100W prototype is presented in experimental condition to certify the validity of the proposed integrated-stage LED driver.
