Abstract: The production of clean electricity is one of the most basic human needs today. Therefore, the use of power plants that use renewable and environmentally friendly fuels (new energy) as their base fuel, has been highly appreciated. However, the output voltage level of local power plants based on new energies is as low as the input voltage of the next floors (inverters, etc.). Therefore, researchers have tried to solve this defect by using DC / DC boost converters. The structures related to these converters are different based on the designer's expectations such as voltage gain, output power, efficiency, input voltage specifications, etc. Boost converters are responsible for increasing the DC voltage by switching and storing energy in their inductor. But the same simple structure can be created with the help of new tricks such as using magnetic coupling, adding passive incremental circuits to the converter structure, creating more complete structures by using several active switches and even combining several structures together to the desired point in terms of voltage gain. On the other hand, with soft switching methods (resonance, snubber, etc.), the efficiency of boost converters is in the acceptable range. In this paper, the types of power plants based on new energy and then boost converters, which are the most basic elements of a power plant based on new energy, it is categorized in terms of incremental structures and applied methods for optimizing these converters, especially in terms of reducing losses and increasing efficiency.
