无电感升压压电谐振器(SUPR)变换器：描述函数分析

A model for an inductorless step-up piezoelectric-resonator-based dc–dc converter is presented. A describing function approach is used to determine the equivalent circuit of the mosfet power stage and resonator, allowing the duty cycles of both mosfets to be accurately estimated. The model provides a method for estimating the output voltage and resonant current of the converter during operation. T...
