| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 106 === Although power converters can reduce the output switching noise under zero-voltage switching conditions, the voltage change slope cross- the switch also becomes larger while the load is heavier and the switching frequency is higher. More importantly, the switching noise increases with it. The main research purpose of this thesis is to study the switching noise interference of DC switching power converters. By analyzing the waveform of the voltage across the inductor, the effect upon the variation the voltage across the switch on the output noise is discussed. In this thesis, a Dual-Active-Bridge Synchronous Rectification Buck (DAB SR Buck) Converter is studied and designed to reduce the output noise, and a Double-Sided Zero-Voltage-Switching (DS-ZVS) control scheme is implemented to further reduce the switching noise. Simulation software SIMPLIS and experiments are applied to verify the proposed converter operated at 1 kW. The experimental results show that over 76.9% switching noise is reduced by the DS-ZVS scheme.
