Control circuit for a sensitive semiconductor device of the thyristor or triac type with an impedance for enhancing self-firing

摘要

Circuit for controlling a semiconductor device (SC), comprising breaker means (M) able to establish a short-circuit between the gate and the cathode of the said device under the effect of an external command, characterised by a resistor (RGa) for enhancing self-firing, connecting the positive pole of the circuit (A) to its gate control output (G).
