Abstract :
Existing firing schemes for the firing of three-phase SCR bridge rectifiers used for industrial applications employ equidistant firing pulses. Mostly they consist of six identical phase control circuits. In this paper a compact scheme using minimum integrated circuit components is described. It has a fast response for triggering angle correction and gives a full range control of voltage.
