Three-Level T-Type Inverter Fault Diagnosis and Tolerant Control Using Single-Phase Line Voltage
2020
IEEE Access
This study combines extension theory and chaos theory to create a three-level T-type inverter fault diagnosis system that uses single-phase line voltage signals. First, the three-level T-type inverter singlephase line voltage output waveform was measured when faults occurred separately in 12 power transistors. Subsequently, the Lorenz master-slave dynamic error transformation was used to obtain the chaos eye coordinates, which functioned as fault characteristics. Fault diagnosis involved
