基于前端串/并联压电谐振器的DC-DC变换器设计与分析

Piezoelectric (PR)-based dc–dc converters present an attractive opportunity to reduce converter costs and size, while simultaneously enhancing efficiency. However, the efficiency of a conventional PR-based dc–dc converter experiences a significant decline when operating outside the nominal 2:1 conversion ratio, diminishing appeal for applications demanding low voltage conversion ratios (VCRs), spe...
