Abstract
This paper presents the PFC method for an electronic ballast using SEPIC converter. Generally, the Boost Converter Type PFC has a DC 400V and output voltage is a bigger than input rms voltage. But the SEPIC type converter has above 0.95 Power Factor and wanted output voltage. This paper employs the SEPIC(Single Ended Primary Inductance Converter) Converter for PFC and the Ring core for oscillating method. Consequently, We reduced element's size and capacity in a converter with minimum voltage for the operating lamp.
