Nowadays, HB-LEDs are discussed noticeable lighting instrument because of their great Longevity, Varicolored, and Compatible withEnvironment. It works by sampling of input and output voltage and current in boost converter, whereupon, improving the input power factor and reduction the line current’s Total Harmonic Distortion (THD). Recently, power factor correction (PFC) has become an essential part of new power supply designs. Proposed converter shows a power supply for HB-LED which could work under a large AC input voltage range and obtains high power quality. It is a single stage, low cost and high efficiency. The UC3854 with fast control loop is used to improve power factor and enabling the PWM dimming. We tested the novel control method by simulating and built both converters in the laboratory and final results compared to open loop converter. Copyright@ International Science Community Association
