Abstract :
Piezoelectric transformer (PT) is attractive to the low power converting applications with advantages of high efficiency, small size, low EMI and high power density. This paper discusses ZVS conditions for a phase-lock control PT DC/DC converter, and we regulate the output voltage with the second loop. A 15 V to 45 V DC/DC converter is implemented with discrete circuit. Finally we show the experimental results
