This paper presents the design of a three-phase T-type three-level inverter, which employs carrier-stacked SPWM (Sine Pulse Width Modulation) modulation. The system hardware comprises an auxiliary power supply module, an IGBT three-phase inverter bridge module, a three-phase inverter drive module, a voltage detection module, an overcurrent detection module, and a post-stage filtering module. In this paper, MATLAB/Simulink is used to model and simulate the T-type three-level inverter circuit. The simulation results confirm that the designed three-phase T-type three-level inverter and its auxiliary circuits can stably output high-quality three-phase AC power, demonstrating the feasibility and reliability of the design scheme.
