Young Tae Jon----Joung-Hu Park-SCHOOL OF ELECTRICAL ENGINEERING SOONGSIL UNIVERSITY SEOUL KOREA
 PURPOSE
 Development of new concept structure, control algorithm and hardware prototype of next generation power conditioner for conversion of paradigm of PV power generation - Design of a new, parallel, integrated, modular, differential power conversion system architecture (shuffler, feedback, feed-forward structure) - Development of a high-power topology capable of maintaining high efficiency at low capacity while implementing the minimum power point tracking algorithm (Anti-MPPT algorithm) for minimizing power capacity, which is an advantage of differential power conversion - Increase efficiency and reduce size using GaN MOSFET or SiC / Schottky diode. - Optimal design of multi-loop feedback controller with stable and fast dynamic characteristics by applying Extra-Element Theorem to multi-module power converters - Proposed theory and performance analysis verification through hardware

 RESULTS Development of Next Generation Parallel Type High Efficiency Differential Power Regulator for Modularization of Photovoltaic Power Generation - Improved reliability and scalability by developing it as a parallel-type instead of a conventional serial type - A multi-winding transformer-type forward and buck converter is proposed to combine magnetizing elements to construct a high-efficiency differential power regulator circuit. : The methodology for achieving the goals was studied as follows. - Dynamic dynamics analysis, controller design and hardware fabrication of multiple module including MPPT algorithm of differential power regulator in the world's first modular PV system structure - Applied the Extra Element Theorem, which was used for the analysis of the complex system of electronics for the first time in the academic world, to the power module, the differential power modulator, and the multi-module dynamic characteristics analysis. - Developed P & O algorithm to specify anti-MPPT concept. - Developed a differential power regulator circuit using various feedback, feed-forward and shuffling topologies.

Expected Contribution

- Advantages of modular photovoltaic power Expected Contribution - Advantages of modular photovoltaic power generation system are cost reduction and efficiency improvement through standardized mass production. Therefore, it is possible to utilize the basic data of basic plan preparation corresponding to standardization of PV industry. - Apply to the environment policy for activation of solar power supply business and low carbon industrialization - Independent photovoltaic technology for satellite power supply is essential for promoting the independence of high-tech space technology currently being promoted nationally. - Wattmeter system technology in the space industry requires high reliability and flexibility (scalability). Therefore, it is possible to acquire proprietary technology by developing a modular parallel solar PV system. - In relation to other energy harvesting issues, solar energy harvesting technique is less likely to succeed than other piezoelectric (vibration) harvesting and thermal harvesting materials. - Using the results of this study, we are promoting the commercialization of the technology through the industry that is currently conducting the photovoltaic project, thereby improving the field feedback and practicality of the research result - Technology Transfer and Patent Transfer - Contributes to the academic development of the new and renewable fields through announcing SCI (annual) thesis
