Abstract
This paper presents a CCFL backlight inverter which uses the quasimodal piezoelectric transformer. The control loop locks the phase difference between input voltage and output current of piezoelectric transformer directly. It can approach the maximum-gain frequency within a range of load resistance value with proper locking phase
