MODEL PREDICTIVE CONTROL FOR 3-PHASE 3-LEVEL DIODE LAMPED INVERTER

Abstract

This paper presents predictive control technique for 3-phase 3-level diode clamped inverter topology. First, the mathematical description of the inverter's structure is introduced. Next, the predictive control algorithm with three goals of current control, capacitor voltage balance, and switching frequency reduction is presented. Finally, the predictive control algorithm for the 3-level diode clamped inverter is verified and evaluated through simulation results by MatLab/simulink software
