| Abstract |
A neutral-point-clamped inverter operated with optimized pulse patterns is considered with an induction machine. For this setup, a control method is proposed that achieves high-bandwidth control of the electromagnetic torque and machine magnetization through stator flux trajectory tracking while balancing the inverter's neutral point (NP) potential. More specifically, a model predictive pulse pattern control problem is formulated and solved that addresses stator flux control and balancing of the NP potential in one single control loop. The proposed controller achieves minimal current distortions per switching frequency and is thus well-suited to medium-voltage power converters operating at low pulse numbers. |
