Abstract :
A novel high step-up high efficiency DC-DC converter for photovoltaic energy conversion is presented in this paper. The proposed converter employs a coupled inductor and two voltage multiplier cells to achieve high step-up voltage gain. The operating principle and the steady-state analyses of voltage gain are described in detail. A 200 W prototype with 20-30 V input and 400 V output voltages is built to verify the analysis. The maximum efficiency of the prototype is nearly 97.7% and the efficiency is higher than 97% over a wide load range.
