| Summary: | 碩士 === 南台科技大學 === 電機工程系 === 101 === This thesis focuses on a bidirectional isolated Dual Active Bridge (DAB)-based dc/dc converter for a battery system. The DAB converter possessing functions of bidirectional power flow, electrical isolation, high step-up ratio, and zero voltage switching, is worthy of applications in such energy storage systems. For performance analysis, input side of the converter is connected to the high voltage DC bus and output side of the converter is connected to the low voltage battery. The DAB-based dc/dc converter consists of two full-bridges controlled by bipolar manner with 50% duty. Power conversion between two dc sides is accomplished by phase shift between the primary bridge and the secondary bridge.
To verify the feasibility of the DAB bi-directional dc-dc converter equipped with lead acid battery as an energy storage device, a 150 W output power will be discussed in this thesis.
