The conversion of a first AC signal into a second AC signal (32) is performed from a first AC signal, from data and from measurement values obtained during conversion. During conversion, switches obtained during conversion. During conversion, Switches are activated with the aid of a computer, which, on the basis of data and measurement values, calculates the necessary frequency and amplitude of the second AC signal (32) at time intervals (A). Control sequences (Q1, Q2, Q3, etc. . . ) are applied to the switches, the latter controlling said sequences during the above-mentioned time intervals (A), in order to produce the second AC signal (32). An output signal of any desired frequency and amplitude shape can thus be obtained, and can also be modified during operation of the transformer.
