![]() The proposed converter consists of two parts and has three power switches. An improved non-isolated DC–DC boost converter, which can be used in the distributed generation or energy storage system in the smart grid, is proposed. A DC–DC boost converter with a voltage extension cell is introduced to reduce losses and voltage stresses on circuit components, this converter has high losses due to a large number of switches in comparison with similar converters. By integrating a capacitor–diode cell into a traditional boost circuit, a higher conversion ratio than the conventional boost converter is obtained. A DC–DC converter with high-voltage gain and two inputs was proposed, which in by adding a snubber cell, the voltage stress on the switches is decreased. The gain of the circuit is increased by adding an inductor and a switch to the proposed converter in and the voltage stress in the circuit elements is reduced. A new DC–DC converter with a switched-capacitor is proposed in, and the dynamic mode of this converter with a switched-capacitor structure has been analysed. By combining the circuit presented in and a switched-capacitor cell, a new structure with a higher voltage gain is presented. The boost and buck converters with switched-inductor cells were proposed in. Two structures asymmetrical hybrid switched-inductor (AH-SLC) and symmetrical hybrid switched-inductor (SH-SLC) are proposed that use four inductors and two switches, which have high voltage gain. In recent years, new methods and structures have been proposed, the important disadvantage of these converters is the high voltage stress on switches and diodes, which increases circuit losses and thus reduces the efficiency of the circuit. To provide the desired high voltage level for load, DC–DC converters are used, there are various types of step-up DC–DC converters such as boost, buck–boost, cuk, and cuk–boost, which can increase voltage. The voltage that is generated by a photovoltaic panel has low level and has variation by change of sun irradiation and temperature. A grid-connected solar photovoltaic system consists of solar cells for energy extraction from the sun and a power converter for grid interface. Owing to the increase in the number of electric consumers, the limitation of greenhouse gases and the high cost of fossil fuels, the use of renewable resources for electricity generation, such as solar power, has been increased.
