To simplify the reset circuitry of multi-phase thyristor inverters having two similar groups of thyristors, one group each controlling the connection of the phases of one polarity, a pair only of reset or quenching circuits are provided, one each output being connected to all the thyristors of a respective group to extinguish the thyristors of the group connected to provide output of the respective polarity during firing thereof. The circuit is preferably connected through an input choke having a plurality of windings in the form of current transformer windings, the additional windings being interconnected with the thyristor circuit to extend current flow through the chokes and provide for smooth commutation. |
