摘要：

This paper presents a novel cost-effective pulse-width-modulation (PWM) dimming method for light-emitting diode (LED) lighting applications. High efficiency, high power factor, circuit simplicity, and low cost can be achieved by a Flyback power factor correction converter with the studied adaptive PWM dimming method. The operation principles and design considerations of the proposed LED dimming method are analyzed and discussed. A 45W laboratory prototype has been built and tested to verify the feasibility of the proposed scheme. Copyright (c) 2013 John Wiley & Sons, Ltd.
