Fault detection of three phase diode rectifier based on harmonic ratio of DC-link voltage ripples

This paper presents a fault detection method for a phase open in three-phase diode rectifier including a DC link reactor to improve the power factor. The fault detection is based on the harmonic components ratio of the 1st and 2nd order harmonics to the 6th order harmonics of the DC link voltage ripples when any one of three phases is opened. The proposed algorithm detects the fault without the information of the load conditions and the performance of the proposed algorithm is verified by the simulation and experiment.
