Three-Phase Interleaved Boost Converter with Fault-Tolerant Control Strategy for Renewable Energy System Applications

This paper proposes a fault-tolerant control strategy for a three-phase interleaved boost converter. The input current and only one inductor current are used to compare with the fault detection signal for the proposed fault detection and failed switch localization method. Once the fault is detected...

Summary:This paper proposes a fault-tolerant control strategy for a three-phase interleaved boost converter. The input current and only one inductor current are used to compare with the fault detection signal for the proposed fault detection and failed switch localization method. Once the fault is detected and localized, the reconfiguration control strategy is applied by shifting the angle between the remaining switching signals. The simulation results show that the three-phase interleaved boost converter with the proposed fault-tolerant control strategy can continue to operate effectively under fault operating conditions
