Abstract

A control and trigger circuit is used for gate controlled rectifiers, particularly those used in oscillators where the triggering level and timing are a function of the load state. The input trigger is fed to the circuit via an optoelectronic diode-transistor pair (12, 17). The output of which provides one input to an AND gate. The second input is derived from a comparator. The two inputs to this are a reference level and a voltage which is a function of that across the controlled rectifier. The rectifier trigger electrode is driven from the logic output via an emitter follower and current limiting resistor and is itself shunted by a series chain of a resistor, diode and capacitor.
