Electronic Ballast Using Neutral Point Type Buck Converter

This paper proposes a neutral point type buck converter circuit that is applicable to an electronic ballast. This circuit is a one-stage converter method electronic ballast, where circuit elements can be reduced by sharing the same switching elements by both converter and inverter circuit and still achieve high circuit efficiency. In this work, the circuit was built and experimented with a fluorescent lamp (NIPPO FLR36T6W) as output load. The proposed Electronic Ballast satisfies the IEC61000-3-2 class C harmonics standard and is suitable for lighting a fluorescent lamp.
