碩士 === 國立海洋大學 === 電機工程學系 === 85 === Abstract In this report, an Auxiliary Switch Assisted Soft Switcher(AASS) is proposed and analyzed. The basic AASS cell includesan inductor, a 'Flying' capacitor and two auxiliary diodes. Theunified analysis of the steady-state processes in a generalizedAASS converter, carried out all power devices and that voltageand current stresses are not appreciably higher than incorresponding hard switched PWM topologies. We derived some useful functions of AASS mode BOOST type dcto dc converter, based on R. D. Middlebrook and S. C'uk statespace averaging, so as to realize the stability analysis of thesystem. Finally, some selected experimental results arepresented to verify the proposed theory.
