Claims
- 1. A gate turn-off thyristor circuit comprising:
- a gate turn-off thyristor;
- a snubber circuit connected in parallel to the gate turn-off thyristor, said snubber circuit comprising,
- at least one snubber diode, and
- at least one snubber capacitor;
- said gate turn-off thyristor, said at least one snubber diode and said at least one snubber capacitor each having electrically opposed terminals or respective contact surfaces and a geometrical major axis;
- said gate turn-off thyristor, said at least one snubber diode and said at least one snubber capacitor connected with each other via electrically conductive plates which essentially extend parallel to each other and which are electrically isolated with respect to each other; and
- said gate turn-off thyristor, said at least one snubber diode and said at least one snubber capacitor arranged so that their respective geometrical major axes are parallel within the gate turn-off thyristor circuit.
- 2. A gate turn-off thyristor circuit according to claim 1, wherein said at least one snubber diode comprises plural snubber diodes and said at least one snubber capacitor comprises plural snubber capacitors, wherein
- the snubber diodes are located at the same distance from the gate turn-off thyristor, and
- the snubber capacitors are located at the same distance from the gate turn-off thyristor.
- 3. A gate turn-off thyristor circuit according to claim 1, wherein the at least one snubber diode and the at least one snubber capacitor have plural symmetrically arranged electrical connections to the conductive plates.
- 4. A gate turn-off thyristor circuit according to claim 2, wherein plural of said snubber diodes are connected in parallel and plural of said snubber capacitors are connected in parallel.
- 5. A gate turn-off thyristor circuit according to claim 2, wherein plural of said snubber diodes are connected in series.
- 6. A gate turn-off thyristor circuit according to claim 4, wherein plural of said snubber diodes are connected in series.
- 7. A gate turn-off thyristor circuit according to claim 2, 4, 5 or 6, wherein plural of said snubber capacitors are connected in series.
