Abstract

In this paper, we propose a modified push-pull electronic ballast that can suppress input harmonic currents. The electronic ballast has partial smoothing function and charge pump function. The behavior of the proposed circuit is analyzed and experimental results are shown. The experimental results show that the circuit can decrease the harmonic distortion of the input current. It is revealed that the harmonic distortion of the input current obtained by the proposed electronic ballast satisfies the maximum limit of IEC 1000-3-2 class C sufficiently. And the electronic ballast realized the high power factor of 0.995 and the high efficiency of 0.88.
