A study of Multiple parallel Characteristics of 50[W] Virtual Implement of 50[W] Solar Cell modules Using Droop-Method

Droop Method를 이용한 50[W]급 태양전지 가상구현장치의 다중병렬연결 출력특성에 관한 연구

For increasing power of photovoltaic systems, serial and parallel connection needed. In parallel connection, a desirable characteristic of parallel-connected supply system is that individual converters share the load current equally and stably. The current sharing(CS) can be implemented using two approaches. The first one, known as a Droop method, and the other is Active current-sharing. In Droop method, current distribution characteristics relies on the high output impedance of each converter. This scheme is more simple and no need interconnections. but also has a disadvantages of degrading current sharing characteristics. In this paper, using droop method at multiful-parallel connection with it's convenience and simplicity.
