In order to address the issue of inadequate voltage gain in conventional two- stage matrix converters

this paper puts forth a novel three- level high gain split- source flying capacitor two- stage matrix converter (TL- HGSSFC- TSMC) and undertakes a comprehensive investigation of its modulation strategy. The converter integrates the functionality of a two- stage matrix converter

a novel high- gain split- source network

and a three- level flying capacitor inverter

with the objective of enhancing the voltage gain and the quality of the output waveform of the converter. The rectifier stage modulation employs a zero- free vector modulation strategy

and the operating principles of the high- gain split- source network and the three- level flying capacitor topology are systematically analyzed. The flying capacitor inverter stage employs the enhanced space vector pulse width modulation (SVPWM) method based on phase- shifted carrier

a technique that effectively addresses the flying capacitor voltage unbalance issue. Subsequent to the theoretical underpinnings

a simulation verification procedure was executed using Matlab/Simulink. The outcomes demonstrate that the proposed converter substantially enhances the voltage transfer ratio and attains a three- level output when contrasted with the conventional topology.
