Generator for power factor 1 arc welding machine

摘要

In the primary winding, of the type comprising a (104) a current transformer that is powered by (101) rectifying unit and the input smoothing, and power factor, and also supplies power to the welding arc in the secondary winding A generator for arc welder, between the current transformer and the rectifier unit and the DC by a combination rectifier stage is connected to the current transformer, the secondary winding of the current transformer (105) / electronic circuit comprising the two electronic switches that constitute the half-bridge structure to perform DC conversion, and a smoothing coil is present, the circuit capacitance of the resonance which is arranged on the side of the primary winding of the current transformer and a combination of an inductive component and sex parts, the part to control the welding current to charge a bank of capacitors that are arranged downstream of the electronic switch, and also maintaining a constant voltage across the capacitor more , and is also provided means suitable to ensure the incorporation of sinusoidal type from the AC power source.
