Sensorless Standstill Diagnosis of Rotating Diode Open‐Circuit Faults in WFSSG via Current‐Vector Modulus

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Open‐circuit faults in rotating diode rectifiers (RDRs) disrupt excitation current in WFSSG systems. A modified rotor current vector modulus (CVM) with harmonic distortion analysis enables accurate fault detection even at standstill, without rotor position sensors.
