System for a Solar Power High-Frequency Converter Operation in Electric Vehicle Application

Abstract

A solar power system is the most reliable and environmentally-friendly form of energy because it is non-polluting, inexhaustible, and non-toxic. Because of the rapid advancement of semiconductor devices and the application of power electronics methods, it is required to maintain the DC maximum power and high output efficiency of solar arrays. The solar power converter operates as a single-stage and single-phase converter on both the transmitter and receiver sides with some parameter configurations. This proposed system mostly utilizes the PV array with the high-frequency inverter integrating the DC-DC converter, which minimizes the converter losses and the current ripple. A high-frequency rectifier can be used on the receiver side of the proposed output circuit to rectify it. By reducing switching and conduction losses, it is possible to increase the output power. This circuit diagram uses a prescribed level of solar irradiance, suitable DC optimal voltage, and optimal AC RMS current to simulate an entire AC cycle. MATLAB/SIMULINK is used to design and simulate the system. Using an irradiance value of 1000 W/m 2 , and a temperature of 20  C, the optimal output values have been obtained and evaluated as 342V DC and 20.05A AC. Thus, the main objective of this paper is to create a highly efficient energy converter to charge EVs with a DC input voltage of 12 V. This converter will have a high-efficiency range of 96 %.
