Wide bandgap semiconductor based power supply assemblies for plasma operating systems and related methods and devices

摘要

In some aspects, plasma torch cutting systems can include a housing and a plasma torch power supply within the housing and configured to generate a signal that initiates generation of a plasma arc in a torch head, the power supply including an integrated circuit comprising a plurality of electronic components used to generate the signal that initiates generation of the plasma arc, at least one of the electronic components being at least partially formed of a wide bandgap semiconductor material.

1. A plasma torch cutting system comprising:
a housing; and a plasma torch power supply within the housing and configured to generate a signal that initiates generation of a plasma arc in a torch head, the power supply including an integrated output circuit configured to receive a signal from an input circuit of the power supply and generate the signal that initiates generation of the plasma arc, the integrated output circuit comprising a plurality of electronic components, at least one of the electronic components of the integrated output circuit being at least partially formed of a wide bandgap semiconductor material, a ratio of a level of nominal power generated by the power supply to a combined weight of the housing, the power supply, and any other components contained within or coupled to the housing being at least 800 Watts per kilogram (W/kg).
