The research in Power Inverter is one of the most rapidly changing technologies in the modern era, with many researchers beginning to replace traditional so-called inverter-based transformers with other sorts of circuits. A major issue with traditional transformers is that they come with a price and occupy up a lot of space. This study will provide a new technique for replacing the traditional transformer idea by combining a dual DC/DC SEPIC converter with a modified H-bridge inverter to create a five-level inverter with multirange voltage selection that is dependent on the duty-cycle of the SEPIC converter. The proposed inverter's input DC voltage is stepped-up, resulting in a five-level output voltage waveform appropriate for driving an AC motor. The recommended inverter is evaluated using a PowerSim simulation with different duty-cycle values.
