Abstract:
PCT No. PCT/DE88/00573 Sec. 371 Date Mar. 16, 1990 Sec. 102(e) Date Mar. 16, 1990 PCT Filed Sep. 16, 1988 PCT Pub. No. WO89/02527 PCT Pub. Date Mar. 23, 1989.A high-voltage switch is suggested which is usable particularly as an ignition voltage distributor for applying the ignition voltage to spark plugs of an internal combustion engine. The high-voltage switch comprises a cascade circuit of optoelectric semiconductor elements which are actuated or connected through by means of incident light radiation. Very high voltages can accordingly be switched in an exact manner, wherein a galvanic separation is provided between control circuit and high-voltage circuit. The control circuit can be operated with low voltage, so that use in connection with electronic ignition systems is particularly simple.
