Abstract

A method and apparatus for operating a DC plasma torch. The power supply used is at least two times the average operating voltage used, resulting in a more stable operation of the torch. The torch can include two concentric cylinder electrodes, the electrodes can be graphite, and the plasma forming gas can be hydrogen. The power supply provided also has the capability of igniting the torch at a pulse voltage of at least 20 kilovolts.

Claims (22)

1. A method for operating a direct current (DC) plasma arc torch, comprising:

operating the DC plasma arc torch using a plasma forming gas and a power supply,

wherein the power supply is configured to supply at least two times an average operating voltage used to operate the DC plasma arc torch, resulting in more stable operation of the DC plasma arc torch including reduced voltage fluctuations and substantially no extinguishing of an arc generated by the DC plasma arc torch, and

wherein the power supply contains inductive filters distributed among positive and negative legs of a regulator to prevent conducted emissions caused by the DC plasma arc torch from feeding back into sensitive electronic components.

2. The method for operating the DC plasma arc torch of claim 1 , wherein the DC plasma arc torch is operated in a power regulating mode where the power supply is operated at a given power setpoint, and wherein the power supply adjusts both the output voltage and the current in order to keep the output power at the given power setpoint.

3. The method for operating the DC plasma arc torch of claim 2 , wherein the DC plasma arc torch is operated with a current setpoint at which the power supply switches from the power regulating mode into a current regulated mode to keep the arc generated by the DC plasma arc torch from extinguishing, and wherein the DC plasma arc torch then raises the current setpoint and switches back to the power regulated mode once the current is high enough to keep the arc generated by the DC plasma arc torch from extinguishing, resulting in the reduced voltage fluctuations and the substantially no extinguishing of the arc generated by the DC plasma arc torch.

4. The method for operating the DC plasma arc torch of claim 1 , wherein the DC plasma arc torch includes concentric cylinder electrodes.

5. The method for operating the DC plasma arc torch of claim 4 , wherein the concentric cylinder electrodes comprise graphite.

6. The method for operating the DC plasma arc torch of claim 1 , wherein the power supply has the capability of igniting the DC plasma arc torch at a pulse voltage of at least 20 kilovolts.

7. The method for operating the DC plasma arc torch of claim 1 , wherein the plasma forming gas comprises hydrogen.

8. An apparatus for operating a direct current (DC) plasma torch, comprising:

the DC plasma torch, and

a power supply,

wherein the power supply is configured to supply at least two times an average operating voltage used to operate the DC plasma torch, resulting in a more stable operation of the DC plasma torch, and

wherein the power supply includes inductive filters distributed among positive and negative legs of a regulator to prevent conducted emissions caused by the DC plasma torch from feeding back to sensitive electronic components.

9. The apparatus for operating the DC plasma torch of claim 8 , wherein the DC plasma torch includes concentric cylinder electrodes.

10. The apparatus for operating the DC plasma torch of claim 9 , wherein the concentric cylinder electrodes comprise graphite.

11. The apparatus for operating the DC plasma torch of claim 8 , wherein the power supply has the capability of igniting the DC plasma torch at a pulse voltage of at least 20 kilovolts.

12. The apparatus for operating the DC plasma torch of claim 8 , wherein the inductive filters cause the sensitive electronic components to be exposed to 50% less energy in the form of voltage or current in an instantaneous or cumulative measurement.

13. The apparatus for operating the DC plasma torch of claim 8 , wherein the inductive filters comprise a filtering element located at an output of a regulator to shunt high frequency energy.

14. The apparatus for operating the DC plasma torch of claim 8 , wherein the power supply contains chopper regulators in a parallel configuration.

15. The apparatus for operating the DC plasma torch of claim 8 , wherein the power supply contains chopper regulators in a series-parallel configuration.
