In recent years, DC distribution systems are gainingmore attention because of their high efficiency, reliability com- pared to AC distribution systems. Integration of lower voltage range renewable energy sources into 400 V dc bus is one of the major challenges to be faced by the power electronic converters. Typical voltage ranges of a solar panel is around20- 30V . Conversion of these voltages to higher voltage rangeby normal boost converters with high duty ratios results in high voltage stresses and lesser efficiency. Since, the output DC voltage from the photovoltaic panel is very low, so a non- isolated interleaved high-gain DC/DC converter with a voltage multiplier cell (VMC) structure is presented. In order to achieve higher voltage gain and to reduce the voltage stress of the switching devices, the proposed high gain converter uses a two phase interleaved technology combined with a boost unit with a common ground, which has smaller input current ripple and gainfeatures of high coefficient. This high gain converter provides high voltage gain at low duty cycles and reduces the voltagestresses on the switches effectively when compared to the other boost converters. Results are obtained by simulating the converter in MATLAB/ SIMULINK R2020b. The simulation results shows that the proposed interleaved high gain converter improved the gain, reduced the stresses in switching devices and achieves a maximum operating efficiency of 85.
