บทคัดย่อ

This paper proposed an electronic ballast that uses an input current shaper to reduce the total harmonic distortion of the line input current, that only process a small part of the total power. Base on the minimum value of the conduction angle to satisfy the requirements of the IEC 61000-3-2 Class-C standard, the conduction loss of the ICS stage can be reduced. The input current shaper is achieved by using a bridge rectifier which acts as the Class-DE resonant rectifier. By using this topology the conduction angle of the diode can be increased to high enough for satisfy the IEC 61000-3-2 Class-C standard requirements. The proposed electronic ballast is designed for 36-W fluorescent lamp and operated at a line rms voltage of 220 V, a line frequency of 50 Hz with the switching frequency fixed at about 76 kHz. The experimental results show that the total harmonic distortion is 29.5%, the power factor is 0.96, a lamp-current crest factor is 1.42, and 95.2% efficiency at full power. ฉ 2012 IEEE.
