Abstract

A new type of Piezoelectric Transformer(PT) converter incorporating the ZVS technique is presented. A combination of the ZVS technique and the PT successfully achieves higher efficiency. For low output voltage, using half-bridge rectifier stage, the converter achieved 72% efficiency, at Vin = 80 V, Vo = 11.8 V, and Po = 5 W; For medium output voltage, using full-bridge rectifier stage, the converter achieved 83 % efficiency at Vin = 80 V, Vo = 40 V, and Po = 10.7 W.
