renewable energy sources such as PV are used as clean energy sources however, these energy sources have a low output voltage, and in high voltage applications step-up DC-DC converters are employed to increase the output voltage of these types of energy sources. In this paper, a non-isolated boost DC-DC converter with a coupled inductor is introduced and analyzed. Unlike previous DC-DC converters, this converter provides high voltage gain with low turn ratio, which reduces the core size, volume and weight of the converter and also reduces the cost of the system. Also, by reducing the turn’s ratio of the coupled inductor, the voltage stress of the semiconductor elements is reduced subsequently. A passive clamp circuit is also applied in the proposed converter, which boosts the converter voltage gain and also, reduces the voltage across of the switches. To demonstrate the advantages of the presented structure, a laboratory prototype is fabricated with 20V input and 200V output voltages and power rate of 200W in 25 kHz operation frequency.
