CONDUCTION-MODE VOLTAGE SOURCE CHARGE-PUMP POWER FACTOR CORRECTION ELECTRONIC BALLAST * Ray-Lee Lin, Hsu-Ming Shih, National Cheng Kung University, Tainan, Taiwan Chen-Yao Liu, Kuo-Bin Liu, National Synchrotron Radiation Research Center, Hsinchu, Taiwan Abstract This paper presents the piezoelectric transformer (PT) based continuous-conduction-mode (CCM) voltage source (VS) charge-pump (CP) power factor correction (PFC) electronic ballast. By replacing L-C resonant tank and transformer in the conventional CCM VS CP-PFC electronic ballast with PT, the cost and volume can be reduced. The experimental results show that the electronic ballast using PT achieve high power factor and the switches can be operated under zero-voltageswitching condition.

Design of a Radial Mode Piezoelectric Transformer for a Charge Pump Electronic Ballast with High Power Factor and Zero Voltage Switching
Electrical Engineering (ABSTRACT) In a conventional electronic ballast for a fluorescent lamp, inductor-capacitor-transformer tank circuit is used. A Piezoelectric Transformer (PT) can potentially be used to replace such a tank circuit to save space and cost. In the past, ballast design using a PT requires selecting a PT from available samples which are normally not matched to specific applicat...
