This paper proposed a design approach for piezoelectric‐transformer‐based power supplies. Initially, an analytical approach is used to derive the Mason equivalent circuit parameters of a PT. This is coupled with a semi‐automated procedure to decide the appropriate physical dimensions of the PT. The procedure is applied to a typical low‐power power supply specification, whereupon a specific transformer is design, verified using COMSOL and used as a simulated converter in SPICE. Results show that the design can be successfully implemented while maintaining efficient zero‐voltage switching operation.
