Summary:PCT No. PCT/DE88/00664 Sec. 371 Date Jul. 24, 1989 Sec. 102(e) Date Jul. 24, 1989 PCT Filed Oct. 27, 1988 PCT Pub. No. WO89/05056 PCT Pub. Date Jun. 1, 1989.A direct current voltage controlled triggering circuit for triacs connected via a consumer resistor to an alternating current supply voltage uses the controllable channel resistance of a field effect rransistor to distribute loading current among a series connection of capacitors connected via a load resistor and the consumer resistor to the a.c. supply voltage. A connection point of the load resistor and a load capacitor in the series connection is connected via a diac to the gate electrode of the triac, and the remaining series connected capacitors have an approximately equal value to provide symmetrization of the current flow phase angle for the diac.
