A Non-Isolated High-Gain Non-Inverting Interleaved DC-DC Converter Multi-Output Network for Renewable Energy Application

Increasing electricity demand can be met with clean energy production using renewable energy instead of conventional fossil fuel-based electricity generation methods to reduce carbon emissions. Utilizing multiple renewable energy sources within a single power generation system is known as a hybrid renewable energy source (HRES) system. The main objective behind the development of HRES is to resolve the intermittency issue of an individual renewable energy source (RES). As researchers are focusing more on the optimum use of energy, they have developed low-power energy-saving appliances operated on DC voltage. In order to meet the applications voltage requirements, different voltage levels are required. This paper proposes a parallel combination of networks to generate multiple output DC voltage levels. The selection of the different voltage levels is based on the standard IEC 60038 of the International Electrotechnical Commission. Each of the networks is comprised of a non–isolated, high–gain, non-inverting interleaved (NIHGNII) DC-DC converter, and for the optimum switching of the (NIHGNII) DC-DC converter proportional-integral (PI) control technique is integrated as a feedback control. Performance evaluation of the proposed system is carried out based on steady-state response under seven different scenarios for all three networks. The maximum steady-state response was observed during scenario 7 for all three networks, for network 1 is 0.17 s, for network 2 is 0.11 s, and for network 3 is 0.13 s. The proposed multi-output power system model is analyzed and investigated with different possible scenarios through software simulation using MATLAB/Simulink environment.
