Analysis of GTO failure mode during DC voltage blocking
GTOs suddenly failed without any leakage current increase before the failure event, during DC voltage blocking. From various experiments and the analysis, we have come to the inference that the GTO failure was caused by cosmic-rays at sea level. The failure rate of the improved GTOs decreases by more than one order.
