The impedance source inverter (ISI) plays a pivotal role in power electronic DC-DC and DC-AC power conversion. ISI offers notable advantages, including single-stage power con-version, buck-boost voltage capability, enhanced voltage gain, and shoot-through immunity. In this paper, a high-gain basic switched boost five-level inverter with dual active state operation is proposed. The proposed inverter is designed by integrating two switched boost impedance networks and cascading them with a hybrid configuration of an NPC inverter and a T-type inverter. The proposed inverter's two active modes of operation provide enhanced modulation index, high voltage gain at low duty ratio, and better DC link voltage utilization. The proposed inverter employs a modified PWM control technique, which lessens the complexity involved in putting the shoot-through (ST) condition in a sine-triangle comparison. A comprehensive examination of the operational principles, meticulous analysis under stable conditions, and detailed exploration of impedance parameter design are provided. Finally, the analysis is validated through MATLAB SIMULINK software results.
