Abstract
A control strategy for piezoelectric transformer DC-DC converters based on a phase and frequency detector circuit is presented. The control always tracks transformer resonance frequency, independently of differences between devices of the same type and temperature variation. Voltage regulation is achieved by adopting the pulse width modulation technique. A prototype confirmed the expected results
