Resumo(s)
Multilevel inverters with three-level T-Type topology are widely recognized as a highly recommended solution for applications that require reliability and fault tolerance. However, achieving a fault tolerant operation system typically requires the implementation of fault detection algorithms along with modulator or control system. This paper proposes a different approach by introducing a self-adaptive control system designed to ensure fault-tolerant operation under open-switch fault conditions. The proposed control system is based on Model Predictive Control (MPC). The proposed controller intrinsically detects deviations from the desired setpoint and automatically cancels the usage of the faulty voltage vectors. Furthermore, the proposed control ensures capacitor voltage balancing, even under fault-tolerant conditions. The effectiveness of the proposed faulttolerant MPC method is demonstrated through several simulation tests. The results obtained confirm the validity and feasibility of the proposed approach.
