| Abstract: | Based on the research of output features and mathematic module of photovoltaic(PV) cells,a simple equation is used to fit the practical I-V characteristic curve accurately.A design of photovoltaic simulator is researched,for which a Buck circuit is used as the main circuit,and also the voltage feedback PI controller is applied.Under the closed loop condition,the steady working point of the photovoltaic simulator agrees with the given practical I-V characteristic curve,proving the practicability of the proposed design. |
