Abstract
A method and apparatus for providing welding-type power and auxiliary power includes an input circuit, a welding-type output power circuit, an auxiliary power circuit, and a controller. The input circuit receives input power and provides power to a common bus. The welding-type output power circuit receives power from the common bus and provides welding-type output power. The auxiliary power circuit receives power from the common bus and provides non-isolated auxiliary output power. The controller controls the auxiliary power circuit and the welding-type output power circuit.
Claims19
A welding-type power supply, comprising:
- an input circuit, disposed to receive input power and provide bus power to a common bus;
- a welding-type output power circuit disposed to receive power from the common bus and provide power to a welding-type output;
- an auxiliary power circuit, disposed to receive power from the common bus and to provide non-isolated auxiliary output power;
- and
- a controller connected to control the auxiliary power circuit and the welding-type output power circuit.
A method of providing welding-type power, comprising:
- receiving input power;
- providing intermediate power to a common bus;
- deriving welding-type output power from the common bus;
- providing the welding-type power on a welding-type output;
- deriving non-isolated auxiliary power from the common bus;
- providing non-isolated auxiliary output power on an auxiliary power output;
- controlling the deriving of non-isolated auxiliary power in response to an auxiliary demand for the non-isolated auxiliary power;
- and
- controlling the deriving of welding-type output power in response to a welding demand for the welding-type output power.
A system of providing welding-type power, comprising:
- means for receiving input power;
- means for providing intermediate power to a common bus, connected to receive the input power;
- means for deriving welding-type output power from the common bus, connected to the common bus;
- means for providing the welding-type power on a welding-type output, connected to the means for deriving welding-type;
- means for deriving non-isolated auxiliary power from the common bus, connected to the common bus;
- means for providing the non-isolated auxiliary output power on an auxiliary power output, connected to the means for deriving non-isolated auxiliary power;
- controlling the deriving of non-isolated auxiliary power in response to an auxiliary demand for the non-isolated auxiliary power;
- and
- controlling the deriving of welding-type output power in response to a welding demand for the welding-type output power.
