In-phase signals (with standard AC line) using Quadrants I
and III
Application of unipolar pulses (gate always positive or nega-
tive), using Quadrants II and III with negative gate pulses and
Quadrants I and IV with positive gate pulses
When maximum surge capability is required, pulses should be a
minimum of one magnitude above I
GT
rating with a steep rising
waveform (
