High current source can be used in different applications in laboratory or industrial process.
As a test power supply for control or metrology we use variable autotransformers that keep the sinusoidal voltage supply and do not induce harmonic distortions on the mains power or the output.
Used in an industrial production process, the source should be able to operate continuously 24h / 24h without external intervention.
The power electronics can replace the variable autotransformer to remove the mechanical movements and reduce maintenance.
A power filter will make the whole compatible with the applicable EMC standard.
