Hogarth, CA Fulop, W Yan, William Fong 2011-06-20T15:05:14Z 2011-06-20T15:05:14Z 1975 http://bura.brunel.ac.uk/handle/2438/5347 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University. Mechanisms of thyristor turn-on wore studied. An attempt was made to relate the ‘on’ plasma spreading velocity to the small signal current gain value of the n-p-n transistor section of the thyristor. The extent to which the thyristor turns on initially largely affects the speed of turning-on the device. A model is proposed to calculate the initial turned-on area of thyristors.
