Title :
Inverting faults in a three phase line commutated DC drive
Author_Institution :
Reliance Electr. Co., Athens, GA, USA
Abstract :
The various factors that result in an insufficient thyristor turn-off time and a resulting inverter failure are discussed. A recommended maximum converter voltage for typical industrial conditions is also presented. Data from a laboratory test setup are tabulated to confirm the results.<>
