Application of the differential power converter in the system of solar power plants

Abstract

An analysis of energy collection architectures for large-scale solar power plants was carried out. The topology of a two-stage differential power converter with the characteristics of a DC collection network, which provides a higher energy output for large-scale solar power plants, is presented. The principle of operation of the converter and the flow of current in the circuit during switching are presented. The calculation of the current balancing and voltage equalization cascades, which process partial power and allow groups of photovoltaic panels to work at maximum power under the influence of environmental conditions, has been calculated.
