Abstract:
A predictive control program for mine high-pressure three-level ANPC inverter based on predictive model control was proposed. The program uses current predictive control to achieve three-level ANPC high dynamic performance and unity power factor control, selects switching state corresponding to voltage vector according to switching device loss. For problem of intensive calculated amount, delay compensation control was adopted. The simulation and experimental results show that three-level ANPC rectifier adopting the proposed control scheme has fast dynamic response, good static and dynamic characteristics.
