ABSTRACT:
This paper presents an enhanced power DC-AC buck converter.The main aim of this research paper is to ensure that the conventional H-bridge DC-AC buck converter is operated practically without delay time between the complementary power switches on the same leg.The enhanced version is realized by serially connecting sized inductor-capacitor-diode topology between the drains and the sources of the high sides of the H-bridge converters. The significant improvement in this kind of converter is that it offers short-circuit immune systems that are not obtainable in the traditional buck DC-AC converter and it triggers the complementary power switches without delay time. The power circuit is obtained by an amalgamation of two Y-closed-up topologies to form an H-bridge converter. The proposed system has a power rating of 3.25 kW, THD of 0.2717%, and pure sine waveforms of output voltage and currentof 311.00V and 10.63A under resistive loads. Under RL loads, it offers 3.25 kW, THD of 0.2807%, and pure sine waveforms of output voltage and current of 297.5V and 10.925A
