Abstract

Large-scale photovoltaic applications were limited to rural homes with an off-grid rooftop PV system and a calculator with a single solar cell. The article introduces a novel DC-DC converter that can considerably increase voltage gain without relying on a transformer. This is accomplished by combining a boost converter with two inductors, a cascaded voltage doubler and a capacitor with switches, resulting in a high-performance power conversion system. The converter offers benefits such as ease of use, high efficiency, reduced component strain, and smaller size and weight. However, the converter’s performance depends on various design factors. First, SIMULINK software is used to simulate the suggested converter mathematically. Then, the drive applications use the recommended work. Finally, the suggested converter was tested in the laboratory using a 585W prototype with a maximum efficiency of 97% for the motor load system.
