碩士 === 大華技術學院 === 機電研究所 === 95 === The main purpose of this thesis is to investigate the noncontact power transfer technology thoroughly, and apply to the switching mode battery charger. First, the operating frequency operated at the minimum transformer primary input VA capacity can be derived in the series-parallel mode noncontact power transfer system. Then, the operation mode in AC output situation at the operating frequency is discussed, and further to extend the operation principle in DC output situation. Next, not only a simple design procedure and some analytic formulas are proposed to simplify the design process, but also the values obtained from this design procedure are adopted to simulate by Matlab and IsSpice. Finally, a prototype of noncontact switching mode charger is implemented for a 24 V 4.5 Ah lead-acid battery to verify the feasibility and correctness of the proposed theory.
