一种新型非隔离低功率无电感压电DC-DC变换器

We present a new non-isolated low-power inductorless piezoelectric resonant converter. The piezoelectric material is used as an energy storage element like an inductance in a classical buck-boost power electronic converter. As opposed to most existing piezoelectric converters, the proposed topology enables to dynamically adjust the output power and ratio keeping a high efficiency for a large range...
