碩士 === 義守大學 === 電機工程學系 === 89 === A forward converter suitable for electric motorcycles is proposed in this thesis. The converter can always provide a stable constant DC voltage for the motorcycle during accelerating or decelerating operation. Voltage stress suppression and energy recovery are achieved by the passive snubber of the main switch. Operation modes of the proposed circuit are introduced. Experimental results of a 12V, 120W forward converter with maximum efficiency of 90.84% are presented. Both of the voltage-mode controlled and the current-mode controlled forward converters for the operation characters of electric motorcycles are compared. The results of the performance comparison can be the referral to choose converters for electric motorcycles.
