摘要： 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.

摘要： Various welding systems that provide communication over auxiliary (50) or weld power lines (42, 36) are provided. The disclosed embodiments may include a multi-process welding power supply (10) that is communicatively coupled to a pendant (48) via an auxiliary conduit (50) that facilitates the exchange of data and power between components of the welding system (10). In some embodiments, the pendant (48) may also include auxiliary outlets (64, 62) that allow an operator to power auxiliary devices (58, 60) at the weld location. The disclosed embodiments further include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Embodiments are provided that also allow for bidirectional data communication over a power line in networked welding systems.

摘要： Methods and systems for creating and controlling an AC output for welding, plasma cutting or heating are provided. One embodiment of the present disclosure achieves a desired square wave AC output and reduces the number of circuit components needed by combining components of a buck converter and a full bridge inverter. Current flow paths through a power control circuit that are generated via switching of transistors in the circuit on and off are provided. In one embodiment, a pulse width modulation leg (24), which controls the level of current flow through an inductor (34), is provided. Certain embodiments include a bidirectional buck converter (26, 28, 30, 32, 34) that converts an unregulated DC flow to a regulated DC flow through an inductor. In one embodiment, a steering leg (46) is provided, which controls a direction of current flow through the inductor (34). Additionally, an output clamp circuit (59), which suppresses the parasitic load inductance during polarity reversal is provided.
