Abstract
Piezoelectric transformers (PTs) reveal a promising potential to replace conventional transformers in driving circuits for switching power applications, e.g. high-side driver for IGBT or MOSFET switches. With the realized driver design it is possible to transfer - galvanically insulated - both energy and information with one single PT. Above all, adapted with resonant driver topologies PTs offer increased efficiencies.
