This paper proposes a linear PFC regulator for LED lighting applications. The proposed circuit is small in size because the circuit structure consists of only semiconductors and resistors without any reactors and electrolytic capacitors. The current bypass circuit which is connected in parallel to the LED string consists of single MOSFET, two zener diodes and two resistors. The MOSFET is operated in an active state by a self-bias circuit. Thus, an external controller and high voltage gate drivers are not required. The proposed circuit is experimentally validated by using a 15 W prototype. From the experimental results, the THD of input current is 5.1% and the power factor is 0.999. In addition, the simulation loss analysis demonstrates an efficiency of 91.6% for a 15.2 W prototype.
