碩士 === 國立成功大學 === 電機工程學系 === 104 === This thesis is aimed to utilize the technology of contactless power transmission and implement contactless power array track with segment -excited overlapping-circle inductive coupled structure for power supply of public transportation. First, to improve the stability of power transmission for moving EVs, overlapping-circle inductive coupled structure array is used to provide a uniform distribution of magnetic field. Second, to raise efficiency of overall system, we designed that segment-excited array track controlled by MCU. After that, the transmitting ability is improved by analyzing resonant circuit. Moreover, overlapping-circle inductive coupled structure array is proposed to provide a smooth magnetic field. Proper parameters of coils and lapping way are decided based on magnetic simulation results, so as to increase tolerance of vertical and horizontal offset for EVs on the power track. Based on the experimental results with 15-cm distance, the maximum efficiency comes up to 89.9% with 360-W output power, and the maximum output power of overall system is 759 W with efficiency of 82.95%.
