Embodiment Construction

[0023] Although the present disclosure has been described with reference to a particular welding-type system having particular circuitry, it should be understood that the invention may be practiced with other systems and other circuitry at the outset.

[0024] figure 2 A block diagram of a welding-type system 200 implementing a preferred embodiment is shown. System 200 includes an input circuit 201 that receives input power. Input circuit 201 may be implemented using an input rectifier such as is known in the art. The input power preferably forms a variable speed motor and variable frequency generator, but can be mains or generator power, single phase or three phase, and any voltage within a wide range of voltages. An alternative proposes receiving a dc input, where the input circuit 201 may filter and pass the dc input. As used herein, an input circuit includes circuitry configured to receive an ac input signal and provide a dc output signal, and may include rectifiers, tr...

Abstract

A method and apparatus for providing welding-type power is disclosed. The apparatus includes an input circuit, a dual boost preregulator, a welding-type output power circuit, and a controller. The input circuit receives input power and provides a rectified input to the dual boost preregulator. The preregulator regulates the input and provides bus power across a positive bus and a negative bus. Thewelding-type output power circuit receives power from the bus and provides to welding-type output power. The controller controls the dual boost preregulator and the welding-type output power circuit.

Description

technical field [0001] The present disclosure relates generally to the field of welding-type power supplies including welding-type power circuits and auxiliary power circuits. Background technique [0002] There are many known types of welding-type power supplies. As used herein, welding-type power means power suitable for arc welding, plasma cutting, or induction heating. Welding type systems are commonly used in a variety of applications and often include an auxiliary output to mimic mains power to power tools, lights, etc. As used herein, a welding-type system is a system that can provide welding-type power, and can include control and power circuits, wire feeders, and accessory equipment. As used herein, utility power is electricity provided by a utility company at a certain voltage and frequency. [0003] Providing welding-type power and systems designed to provide welding-type power present some unique challenges. For example, most field power supplies are dedicate...
