Abstract
A welding-type system and method for operating a welding-type system is disclosed. The system includes a switched power delivery circuit connected to deliver power to output terminals and an open-circuit voltage (OCV) control circuit configured to adjust an operational state of the switched power delivery circuit. A controller is included that is configured to monitor the output terminals to identify an open circuit condition and selectively engage the OCV control circuit to adjust the operational state of the switched power delivery circuit to reduce a voltage of the output power delivered to the output terminals during the open circuit condition.
