An Amorphous Alloy Core Medium Frequency Magnetic-Link For Medium Voltage Photovoltaic Inverters, Md Rabiul Islam, Youguang Guo, Zhi Wei Lin, Jianguo Zhu
Faculty of Engineering and Information Sciences - Papers: Part B
The advanced magnetic materials with high saturation flux density and low specific core loss have led to the development of an efficient, compact, and lightweight multiple-input multiple-output medium frequency magnetic-link. It offers a new route to eliminate some critical limitations of recently proposed medium voltage photovoltaic inverters. In this paper, a medium frequency magnetic-link is developed with Metglas amorphous alloy 2605S3A. The common magnetic-link generates isolated and balanced multiple DC supplies for all of the H-bridge inverter cells of the medium voltage inverter. The design and implementation of the prototype, test platform, and the experimental test results are analyzed and …
