Development of Electronic Ballast for a Compact Lamp Based on the Neutral-point-type Back-boost Inverter

摘要

References(4) Cited-By(1) This paper presents new circuit of the electronic ballast based on neutral-point-type back-boost inverter for compact fluorescent lamps. Electronic ballasts for compact fluorescent lamps don't need to satisfy the IEC standard Class C, and the regulation is looser than it. However, it is important to reduce the harmonics of input current, because the compact fluorescent lamp seems to be used widely in future. This paper shows analyses of circuit operations and experimental results, and proves that the proposed circuit is effective for reduction of harmonics of input-current and also effective for improvement of input power factor.
