AC-DC and AC-AC convertors

Giussani offers a wide range of AC/DC and AC/AC converters designed to meet the most diversified needs of energy companies and industrial complexes, small, medium and large.
The Lainate company operates not only at the provincial level and in the Milan area, but also nationally and internationally, thanks to a capillary sales network and excellent quality products for power electronics, the branch associated with conversion electronics for the control and variation of inbound or outbound power supplies.
Thanks to our converters, you can change the voltage, current and frequency from a few milliwatts for small equipment to many megawatts for large machinery and transmission systems.
By applying the power electronics to large structures the efficiency of the entire system can be improved using the best alternative energy: energy savings resulting from the optimization of resources.

 

Power converters: fields of application

Power electronics systems have diverse application areas; AC/DC converters for example are present whenever an electronic device such as computers, televisions, stereo, battery chargers, systems and speed governors applied in industrial electric motors are plugged in.
Such products can be classified into different families according to the type of input power and output. We offer in any case:

  • rectifier systems from AC to DC;
  • inversion systems from DC to AC;
  • conversion systems, chopper or switching power supplies, DC to DC;
  • conversion systems, cycloconverter and cycloinverter, AC to AC.
