摘要：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.
