Abstract
High Brightness Light Emitting Diodes (HB LEDs) are likely to be used for general lighting applications due their high efficiency and longer life. The paper presents a quasi-active power factor corrector (PFC) for driving a string of HB LEDs. The single-stage PFC circuit has a high efficiency and it does not increase the voltage/current stress on the active switch used in the switching converter driven by the PFC. The operation of the converter system for the LED is explained and experimental results are presented.
