Abstract :
In this paper, a multiple-input high step-up boost converter is presented for grid-connected photovoltaic power generation system. Firstly, the derivation of the converter with dual input is presented and its operation principle and steady state performance arc analyzed in detail. Secondly, the n-input high step-up boost converter made up of n boost cells is deduced. Its high step-up ratio and the relationship among the input currents are analyzed. Finally, an experimental prototype rated 100 W is built and the experimental results are given.
