In the College of Engineering, University of Kufa, a master’s thesis was discussed by student Maytham Sadiq Jabbar Al-Madani from the Department of Electronic Engineering and Communications on (Design and construction of a multi-output continuous inverter equipped from a solar cell energy source to feed multi-capacity loads), which was supervised by Asst.prof. Dr.. Amal Ahmed Reda.
This study focused on the process of designing four outputs to be provided from a single input DC power inverter. The proposed transformer architecture has fewer power switches than a conventional transformer. This reduction in switching devices leads to lower costs and higher efficiencies. The proposed transformer is designed using a synchronous non-isolated step-down step-down changer with four outputs of 18.5V/3.3A, 15V/1.5A, 12V/2A, and 5V/2A from a single 48V input. These various values of voltages and currents were obtained from the recommended transformer structure and were mathematically analyzed, simulated and modeled in the MATLAB / Simulink system, and the results were verified. Continuity of power supply for loads. And the use of efficient MPPT algorithm to track the maximum power of the PV panel, which is a stepwise connection algorithm. The system is tested under various.
The results show that the recommended design has a low amount of ripple in output voltage and current in addition to low cost, flexibility and an overall efficiency of 96.9%. Firstly, the results show its durability to sudden change in inputs, voltage problems and intermittent processing of solar radiation levels (1000,800,600 and 400) W/m2 also in the zero radiation condition.
The results show that the efficiency of the MPPT algorithm is (99.9%, 99.7%, 99.4% and 98.6%) for different radiation levels, respectively.
