Coupled Inductor Assisted High-Voltage Gain Half-Bridge Z-Source Inverter

A half-bridge-based impedance-source inverter with two T-shaped coupled inductors is proposed in this article. Unlike the conventional half-bridge structure, topology can generate a zero-voltage level at its output stage. First, configuration and modulation method are described, which will analyze topology's various operational modes. Second, boost factor determined, way to design necessary passive devices found. Third, power loss breakdown study investigated order devise solution improve efficiency of structure. Fourth, comparisons show benefits drawbacks presented design. These that provide high when used. Furthermore, it has reduced voltage stresses on components, resulting smaller size lower cost. Finally, experimental results obtained by employing prototype designed methodology used as benchmark determine whether works well. In addition, analysis comparison displayed.
