ABSTRACT:
Circuit arrangement for controlling a triac.
Triac control circuit with a mechanism (6) for sensing the gate voltage of a triac (2) and a gate pulse generator (11) responsive to the means for sensing. The gate voltage depends on the current through the triac and changes from a higher voltage value for a large triac current to a lower voltage value for a triac current closer to the triac holding current. By sensing the gate voltage it is possible to anticipate the triac turnoff and to generate a triac gate pulse before the triac turns off.
