  • Robust AC chassis fault detection using PWM sideband harmonics
    Patent number: 8278934
    Abstract: A method, apparatus and computer program for detecting an AC chassis fault on one or more DC/AC converters having a load is disclosed, including receiving a chassis voltage VChassis signal from between DC link and a chassis ground from the DC/AC converter, capturing a side band harmonic of the chassis voltage VChassis signal, determining a peak magnitude value related to the side band harmonic, comparing the peak magnitude value to a predetermined threshold value, wherein if said peak magnitude value equals or exceeds the predetermined threshold value, an AC chassis fault condition is detected.
    Type: Grant
