无电感压电变压器软开关电压调节：循环模式分析

This article describes a novel methodology for predicting the ability of an inductorless-driven piezoelectric transformer (PT)-based H-bridge inverters to simultaneously achieve zero-voltage switching (ZVS) and output regulation. A new idea for output voltage regulation by controlling deadtime interval is presented. A model is derived using cyclic-mode analysis to estimate the state-variable param...
