The universal converter device with an impulse sequence in the shape of a cosine wave, transforms the electric energy of the one-phase or three-phase net into a bipolar or alternate tension in the shape of a cosine, with a variable one-phase, two-phase or three-phase frequency, from zero to the net frequency, on differentiated loads, making use of phase shifters (P) and/or counters (CO) for defining the ignition moment ( alpha ).
