Abstract: (46 Views) |
One of the most popular and accessible sources of renewable energy is solar energy. In order to eliminate fossil fuels that have pollution and destructive effects on the environment, many researches and studies have been conducted so that clean sources of energy, including solar energy, can replace or compete with fossil fuels. In a single-phase system with a two-phase structure, if the line voltage is 220 volts, the bus voltage of the inverter connected to the grid must be around 380 volts. However, the output voltage of photovoltaic cells is generally lower than the bus voltage. DC-DC converters with high voltage gain are responsible for converting the low voltage of solar cells to the appropriate voltage level. The boost converter is the simplest structure that increases the voltage level, but the use of the boost converter in high voltage applications will bring many problems, for this reason, extensive research has been done to improve the problems of the boost converter and provide new structures. In the proposed structure, the technique of voltage multiplier circuit and coupled inductor is used to increase the gain. In this article, in addition to explaining the operation of the circuit and providing theoretical analysis, the correctness of the operation of the circuit is evaluated through PSpice software and the practical implementation of the laboratory sample.
