摘要： Enhanced power factor correction for a welding-based power supply includes a controller that tracks a rectified input voltage waveform and detects zero-crossing events therein. The controller generates an ideal sinusoidal current reference signal synchronized by expected zero-crossings in the supplied power. The reference signal is used in a current control loop within the controller to control the power electronics such that the waveform of the current drawn by the power supply matches the waveform of the input voltage. The frequency of the supplied power may be calculated using the expected zero-crossings and used to adjust the expected zero-crossings.

摘要： A welding-type power source includes a primary inverter (20) configured to generate a first AC power and a transformer (tx1) having a primary side configured to receive the first AC power and a secondary side configured to deliver a second AC power. The welding- type power source further includes a converter (18) configured to convert the second AC power to DC power and a half-bridge inverter configured to receive the DC power and having a first output and second output configured to deliver respective portions of an AC welding-type power to a welding output to generate a welding-type arc during a welding- type process. An inductance (L1) is connected at a first' end to the first output and the second output of the half-bridge inverter and connected at a second end to the welding output. Additionally, a circuit (26) is included that is configured to receive an energy stored in the inductance during delivery of one portion of the AC welding-type power and deliver the energy back to the inductance during delivery of another portion of the AC welding- type power.

摘要： A method and apparatus for providing engine driven welding-type power supply includes an engine, a generator, an input power circuit, a welding-type power circuit, an auxiliary power circuit and a controller. The generator includes permanent magnets that create and provides a generator output from at least one polyphase winding. The input power circuit is connected to the generator output and the welding-type power circuit is connected to the input circuit, and provides a welding-type output. The auxiliary power circuit is connected to the input circuit and provides an auxiliary power output. The controller is connected to the auxiliary power and the welding type power circuits, and can command that there be no load for the generator. The generator is connected to the engine and connected to function as a flywheel to the engine and the engine does not include a flywheel other than the generator.
