Abstract :
Piezoelectric transformers (PTs) have lately been looked upon as an attractive solution to reduce size and weight in AC/DC converters. This paper presents a topology that includes such a device while minimizing the number of additional components required for an adequate performance. An 8-watt AC/DC adapter (110 VAC, 12 VDC ) operating at frequencies around 500 kHz is obtained using this topology
