Abstract: In this paper, a fifteen-level inverter is developed and applied for injecting the real power of the renewable power into the grid to reduce the switching power loss, harmonic distortion and electromagnetic interference caused by the switching operation of power electronic devices. The input of the dual-buck converter is two dc capacitor voltage sources. The objective is to develop a low cost, reliable and efficient photovoltaic power supply unit for domestic applications..............
