DC and Pulsed DC TIG Welding with a Scalable Power Supply
A multiple two-phase resonant converter module connected in parallel is the chosen architecture for a TIG welding power supply. Connection to the utility is performed through a front-end power factor correction stage. Fine tuning is performed by overlapping the control signals of the resonant converter phases. Output ripple is reduced by interleaving each module and the arc strike is achieved with no extra circuitry and at low voltage. DC and multiple pulsating operations from 20 Hz to 5 kHz with different pulse widths have been tested. The resulting arc stability, welding parameters and efficiency are analyzed. The experimental results show the welding performance and near unity power factor.
