One-stage Converter Method Neutral Point Type Voltage Free Converter and Application to an Electronic Ballast

摘要

References(6) Cited-By(1) A new neutral point type converter circuit with 200V and 100V input voltage tolerance is developed for application as 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 suitable for lighting a florescent lamp.
