These days, high gain DC-DC converters are re- quired due to the growing usage of solar energy resources. Low efficiency and increased voltage stress are the results of employing a traditional boost converter running at a high duty ratio to achieve high gain.The suggested converter is made to have a low duty ratio, less voltage stress, and a high gain. In order to create this construction, a voltage multiplier cell is added to the rear end of a traditional buck boost converter using a capacitor and diode. This lowers the voltage stress across the switches. Switches with low voltage ratings can thus be utilized.Additionally, a suggested converter that satisfies every need for DC-DC converters in solar applications is examined. This converter has the features of a broad voltage conversion range, constant input current, and high conversion efficiency. A detailed analysis is conducted of the converter's steady-state features and principles of operation. By modeling the converter in MATLAB/SIMULINK R2017b, results are obtained. According to the simulation findings, the converter reaches a peak efficiency of 85% and has a significant voltage gain. A TMS320F28027F microcontroller is then used to implement the hardware prototype with a 2V input, yielding an output of 8.5V.
