In Solar panel and UPS, high gain DC-DC converters are commonly used. In grid connected inverter specifications, the batteries and solar panel voltage level are low. The use of multiple series related DC batteries and PV panels directly connected to the inverter, it simplifies the process, but the expense is high, and efficiency is low. A high-gain Quadratic Boost Switched Capacitor Converter is proposed in this paper. The high step up voltage gain is achieved by adding the voltage multiplier topology in the conventional quadratic boost converter with the correct duty ratio. The fractional order controller is implemented, and it’s tuned by genetic algorithm optimization method for improving the performance of the proposed converter. Its characteristics are low energy processing, robustness and balanced voltage of cells. The performed that include the proposal and existing solutions, the theoretical results are verified from MATLAB/SIMULINK toolbox.
