DC‐DC parallel legs linked high gain converter for microgrid applications

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract For microgrid operations, this article suggests a DC‐DC Parallel Legs Linked High Gain Converter. To realize high voltage gain, the recommended converter is transformer‐free and developed with n$n$‐parallel legs. One active switch, one capacitor, one inductor, and one diode make up each leg of the boost converter.
