Recently, it is often observed that the harmonics interference occurs in the AC power line because switching mode inverter and converter have been widely used as power supplies of the electronic and electrical equipment. In order to prevent this harmonics interference, the guideline on the maximum limits of the harmonics distortion factor of the input current was indicated.
In this paper, we propose an electronic ballast with a boosting function that can reduce the harmonics distortion and can work well under 100V of commercial AC power source. The behavior of the circuit is analyzed and experimental results will be 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 0.96 and the high efficiency of 0.90.
