Hi everyone,
I noticed recently that some researchers in Electrical engineering are trying to detect and localize a faulty power switch in a three phase inverter. However, in the case of a short circuit fault (of a power switch), the current in the DC link increases enormously in a very short time ! so, practically, there is no time neither to detect nor to localize, .. the protection will just shut down the whole thing.
What are your opinions about this ?
see the picture bellow.
