碩士 === 國立臺灣海洋大學 === 電機工程學系 === 101 === Abstract The purpose of this thesis is to analyze the operation of the bidirectional Buck-Boost converter and conversion efficiency, and to explore the process of zero-voltage switching, Buck mode and Boost mode switching element driving voltage and the voltage across the switching waveform. Consider the effects brought about by the resonant capacitor, arising from the use of parasitic elements with resonance technology zero-voltage switching to reduce switching losses, and reduce the adverse effects caused by the parasitic elements and improve the conversion efficiency. When fully loaded, it can improve the stability of the system. Use of IsSpice software simulation of this circuit converters discussed in the case of the CCM and DCM, the waveform of the voltage and current of the converter element of this circuit.
