Abstract

Nowadays, the inverter for CCFL(Cold-Cathode Fluorescent Lamp) driver is needed as form of compact size, low loss and high efficiency. This paper deals with comparison of characteristics of the electromagnetic push-pull type inverter and the piezoelectric half-bridge inverter for a CCFL driver. From the experimental results, the piezoelectric inverter is proven as more efficient than conventional electromagnetic inverter.
