Abstract	This study presents an integrated-stage AC–DC lighting-emitting diode (LED) driver based on flyback and Class-E converter with high power factor (PF) with a wide range of the duty cycle. The flyback circuit works in discontinuous conduction mode to realise the PF correction function, and the Class-E circuit is used as DC–DC converter to transfer the energy to the LED load. By sharing the common switch of the two circuits, the cost of system can be decreased distinctly. In addition, the Class-E converter provides soft-switching operation in a resonant mode, which can improve the converter efficiency. By integrating the flyback and Class-E converters, the soft-switching characteristic is still kept. In addition, the LED driver can be operated with wide duty cycle range to achieve a design degree of freedom to regulate the output current at a constant working frequency which makes the design of EMI filter easier. The operational principles, detailed analysis and design considerations of the LED driver are presented. A 100 W prototype is presented in an experimental condition to certifying the validity of the proposed integrated-stage LED driver.
