Model Predictive Pulse Pattern Control of Medium-Voltage Neutral-Point-Clamped Inverter Drives

Model predictive pulse pattern control (MP
³
C) combines the dynamic performance of direct torque control with the superb harmonic performance of optimized pulse patterns during steady-state operation. In doing so, MP
³
C maximizes the effectiveness of variable speed drive systems by fully utilizing the capability of the power electronic hardware and the electrical machine. Experimental results for a medium-voltage neutral-point-clamped inverter driving a 3.3 kV induction machine rated at 1140 kVA are reported, and the customer benefits of MP
³
C are discussed in detail.
