Abstract
A high frequency power source configured to provide a variable voltage output is described such as for use in welding systems. The high frequency power source charges a capacitive storage device. A transformer having a primary winding coupled to the output of the high frequency power source and establishing a resonant frequency signal with the capacitive storage device, and a secondary winding coupled to the welding power supply, superimposes the resonant frequency signals onto the welding power signal of the welding power supply during periods of the resonant rings. By varying the voltage output from the high frequency power source, the high frequency energy delivered to the welding torch can be optimized for a variety of welding applications.
