MULTIVOLTAGE WELDING APPARATUS |
摘要 |
An apparatus may include an input circuit to receive an AC input voltage having a first magnitude within a range of AC input voltages, and generate a first DC voltage; a boost converter to receive the first DC voltage and output a second DC voltage having a fixed magnitude that is not dependent upon the first magnitude of the AC input voltage; an output circuit to receive the second DC voltage and convert the second DC voltage into welding type power; a control DC-DC converter to receive the first DC voltage and output a control power signal as a third DC voltage; a boost converter control component to receive the control power signal and generate a control signal to control operation of the boost converter; and an auxiliary AC power source to receive the second DC voltage output by the boost converter and to generate an AC auxiliary output voltage. |
