Abstract: Systems and methods to reduce magnetic flux in a switched mode power supply are disclosed. An example welding-type power supply includes a switched mode power supply, including a transformer configured to transform an input voltage to a welding-type voltage; switches configured to control a voltage applied to the primary winding of the transformer; a current detector configured to measure a current through the primary winding; a flux accumulator configured to determine a net flux in the transformer based on a number of volt-seconds applied to the primary winding of the transformer; and a controller configured to: control duty cycles of the switches based on the net flux; and set a value of the net flux in response to the current through the primary winding satisfying a current threshold.

Abstract: Systems and methods to estimate magnetic flux in a switched mode power supply are disclosed. An example welding-type power supply includes a switched mode power supply, comprising: a transformer configured to transform an input voltage to a welding-type voltage; a capacitor in series with a primary winding of the transformer; and switches configured to control a voltage applied to a series combination of the primary winding of the transformer and the capacitor; a voltage estimator coupled to the transformer and configured to output a signal representative of an alternating-current (AC)-coupled voltage at the capacitor; and a flux accumulator to determine a net flux in the transformer based on the voltage applied to the series combination of the primary winding of the transformer and the capacitor

Abstract: A welding-type power supply including a balanced plate rectifier to rectify high frequency alternating current from one or more transformers. The balanced plate rectifier includes an output terminal symmetrically connected to the plates of the plate rectifiers. The impedance between the output terminal and each plate is substantially equal.

Abstract: A welding-type power supply that receives alternating current (AC) input power and converts the AC input power to direct current (DC) power to provide power for welding tools. The welding-type power supply is configured to detect whether single phase AC power or three-phase AC power is connected to the input of welding-type power supply. Single phase input power may be detected by sampling ripple voltage of the DC power, either synchronously with the AC input power or synchronously with a signal generated by an output of the welding-type power supply.

Abstract: Systems and methods are disclosed for automatically activating or deactivating a gouging torch. In particular, the disclosed systems and methods activate and/or deactivate a gouging torch based on a valve operation selection. For example, for welding power supplies and/or welding wire feeders configured to operate both wire welding processes as well as gouging, a valve can be integrated with a gouging torch, which can be adjusted to allow or arrest the flow of compressed air to the gouging torch. In response, the welding power source and/or welding wire feeder automatically changes one or more output characteristics, to switch between a wire welding process and a gouging process without requiring the operator to interact with either the welding power source or welding wire feeder.

Abstract: A welding-type system includes a power supply configured to control preheating of an electrode wire. A controller is configured to receive a plurality of power values corresponding to a power output of the power supply and calculate an arc power value corresponding to an arc condition at the preheated electrode wire based on a rate of change of the plurality of power values. A target power output value is determined based on the calculated arc power value, and the power output is adjusted based on the determined target power value.

Abstract: A method and apparatus for providing welding type power includes a phase shifted double forward converter having a first and second converter with a controller and an output rectifier. The output rectifier has at least one cathode current path that creates a cathode magnetic field when current flows in the cathode current path. The output rectifier also has at least one anode current path that creates an anode magnetic field when current flows in the anode current path. The cathode current path is disposed and oriented and the anode current path is disposed and oriented such that the cathode magnetic field acts to at least partially cancel the anode magnetic field.

Abstract: Apparatus, systems, and/or methods are disclosed relating to a welding-type power supply with a pre-regulator circuit configured to provide a pre-regulated direct current (DC) bus at two or more voltage levels, responsive to various operating conditions. In some examples, the pre-regulator circuit may be configured to provide a pre-regulated DC bus voltage at one voltage level for certain input line voltages, weld processes, and/or target weld output levels, and at another voltage level for other input line voltages, weld processes, and/or target weld output levels. In some examples, the pre-regulator circuit may be configured to provide a pre-regulated DC bus voltage for certain input line voltages, weld processes, and/or target weld output levels and an unregulated DC bus voltage at other input line voltages, weld processes, and/or target weld output levels. In some examples, the pre-regulator circuit may be configured to provide a pre-regulated DC bus at a service voltage in response to detecting a service mode of operation, and/or at an idle voltage in response to detecting an idle mode of operation.
