Abstract :

Today, solar arrays, fuel cells and wind energy are highly regarded as sources of clean energy. These sources can deliver their energy to the grid or directly to the consumer. Usually the voltage level produced in these sources is low and the need to increase the voltage level is. To solve this problem, high voltage gain converters can be used as single-port and multi-port. In the proposed converter to increase the voltage gain, the voltage multiplier circuit, the switched inductors and the switched capacitor are used, and also the clamp circuit is used to solve the problem of energy stored in the leakage inductor. One of the features of this converter is to share the components of the converter in different modes. This is important to reduce the number of semiconductor elements in the construction of the converter. In the proposed converter, the power transfer can be from solar array to load or from solar array to battery or both. Also, in peak moments, solar array and battery consumption can provide load power at the same time. In this paper, theoretical analysis has been used to evaluate the performance of the proposed converters and the results of the converter simulation in Orcad software have been presented to evaluate the accuracy of the theoretical analysis. Finally, a laboratory sample of the proposed converter with a power of 200 watts and a frequency of 100 kHz has been implemented,
