| Summary: | 碩士 === 南台科技大學 === 電機工程系 === 100 === This thesis focuses on the research of a Quasi-Z-Source continuous input current (CIC) converter related to the traditional Z-Source converter. It is a new topological structure with two inductors and two capacitors which is similar to the traditional Z-Source converter, however the power switches states including the non-short circuit state and the short circuit state, can effectively enhance the controlled DC link voltage range. Additionally, the Quasi-Z-Source is a continuous input current (CIC) converter which inherits the advantages of traditional Z-Source converter, thus it is suitable for the dc source with a wide voltage variation. The researched framework is consisted of a DC source input, then following by the Quasi-Z-Source network and the high-frequency insulated based DC-DC converter in order to achieve the regulated output voltage. Finally, the theoretical analysis and design is verified by the experimental prototype to confirm the proposed control idea.
