Abstract
A method and apparatus for providing welding-type power is disclosed. The power supply has two output lines, and two inductances that are magnetically coupled, or a common mode inductance, in the output lines. The inductances may be installed when the power supply is built, or added afterwards. The inductance may protect the welding-type power supply from high frequency noise on a workpiece.
Claims21
A welding-type power supply having an output across first and second output lines, wherein the first output line includes a first inductance and the second output line includes a second inductance, and further wherein the first inductance and the second inductance are magnetically coupled.
A welding-type power supply having an output across first and second output lines, wherein the first and second output lines include a common mode inductance.
A welding-type power supply having an output with an inductance that protects the welding-type power supply from high frequency noise on a workpiece.
