One-port piezoelectric resonators and two-port piezoelectric transformers have demonstrated strong potential as alternative passive components for power conversion. However, their utility is inherently limited to single- input single-output power conversion applications. In this work, we propose a differential power processing (DPP) architecture that leverages one multi-port (≥ three ports) piezoelectric component. The proposed design conditions for multi-port piezoelectric components and DPP converters are validated experimentally in a three-port DPP converter.
