What power quality standards did the semiconductor industry establish?
A.The industry established that power disturbances must be limited to less than 10 volts in the normal mode (phase to neutral) and less than .5 volts (1/2 of one volt) in the common mode (typically neutral to ground). In addition, the industry established that these criteria must be met even though power disturbance might be as large as 6000 volts as defined by the IEEE (Institute of Electrical and Electronic Engineers) in their guideline labeled IEEE C62.41.
