A piezoelectric transformer (PT) converter with PWM control is presented. The combination of an active-clamp circuit and a resonant circuit makes it possible to control the output voltage of the PT converter with PWM at a constant switching frequency. The PT converter circuit is evaluated using an AC analysis, and a design procedure is presented. The PT converter implemented on a printed circuit board is experimentally evaluated and a good controllability is successfully achieved.
