Abstract :
Piezoelectric transformers (PTs) are an attractive solution to reduce size and weight in AC/DC power converters. In this paper, a PT-based topology is presented together with a control method. As an application, an 8-watt AC/DC adapter (110 VAC input, 12 VDC output) is presented operating at frequencies around 500 kHz
