<p>A welding generator with active filter, comprising a rectifier block (A) which is powered by the mains and is connected to an inverter block (B) which is in turn connected to an output diode block (C) and an active filter block (D) is provided which branches off in parallel to the input of the rectifier block, said filter block determining a current (I2) with a waveform which, added to the current (I1) of the rectifier block (A), generates as a resultant a waveform (I3) which is sinusoidal as seen from the mains. <IMAGE></p> |
