新型可调压电变压器及其在DC-DC变换器中的应用

This paper introduces a new tunable piezoelectric transformer (TPT) and demonstrates its operation in a dc–dc converter application. Piezoelectric transformers (PTs) have been conventionally used in high-voltage, low-power applications such as electronic ballasts. Recently, radial type PTs have been developed for higher power ac–dc and dc–dc step down applications. Based on the latter, a new TPT h...
