基于模型预测的单相三电平逆变器电压平衡控制

Neutral-point voltage balance is critical for safe operation of single-phase three-level inverters. This issue can be overcome by selecting proper redundant small vectors. However, two voltage sensors are usually required to sample the split dc-link voltages. This letter proposes a model predictive-based voltage balancing method to reduce the usage of the voltage sensors (saving one voltage sensor...
