摘要：

This paper proposes an effective model predictive current control (E-MPCC) method for grid-connected quasi-Z-source T-Type inverter(QZSTI), which has a purpose of neutral voltage balance and eliminates the weight factor. The inductance current and capacitance voltage are controlled simultaneously using an enhanced sliding mode control technique to prevent the weight component in the cost function. Additionally, a sector selection approach that is accurate and efficient is suggested, avoiding the need for numerous calculations to perform each optimization individually. Results from simulations and experiments support the efficacy and supremacy of this approach.
