碩士 === 國立成功大學 === 電機工程學系 === 103 === This thesis is aimed to design a hybrid power supply system with a capability of energy regulation. With a design and control made in this approach, the proposed hybrid power supply is suitable for the task under different load variations. In this system, the leakage inductance and magnetizing inductance of the transformer are served as energy storage devices, hence reducing the volume of circuit and the number of series supercapacitors while the cost of the proposed circuit is largely reduced. It is also found that the energy flow in the circuit is well supplied with the cooperation of both batteries and supercapacitors, and the current variation of battery modules is thus effectively restricted. To validate the feasibility of the proposed method, both circuit realization and experiment measurements are made. Test results confirm the feasibility of the proposed supply system, meanwhile serving as benefiting references for green energy applications.
