    • The present invention pertains to a commutator containing a semiconductor operable with unidirectional current and bidirectional voltage and with controlled interruption and automatic ignition, and in which a semiconductor device with controlled commutation is utilized. In accordance with the invention, the commutator includes a logic gate (61) having an input which, when the anode-to-cathode voltage of the semiconductor device (2) is below a specific positive voltage close to zero, receives a logic signal from an adapting circuit (4) connected to the semiconductor anode. The other input of the logic gate receives a control logic signal, and the output of the gate is connected to another adapting circuit (5) which converts the logic signal output by the logic gate into a suitable control signal which is transmitted to a the control terminal of the semiconductor device (2). In a preferred embodiment the logic gate (61) is a "NOR" gate and the semiconductor device (2) is a thyristor with controlled commutation, known as a G.T.O. thyristor.
