Claim 2:
3. The method as claimed in claim 1, wherein the applying the control frequency comprises:
defining a frequency increment step;
initializing the control frequency to an initial control value that corresponds to the control frequency calculated by the calculating;
defining a first threshold value and a second threshold value, and an additive inverse of the first threshold value and an additive inverse of the second threshold value;
calculating an error value between a measured input voltage value and said setpoint input voltage; and
comparing said error value with said threshold values; and
wherein the method further comprises regulating during which:
when said error value is between the first threshold value and the additive inverse of the first threshold value, and when said error is higher than the second threshold value or lower than the additive inverse of the second threshold value, the control frequency is incremented by the frequency increment step;
when said error value is between the second threshold value and the additive inverse of the second threshold value, the control frequency is kept at its previous value; and
when none of these conditions is met, the initial control value is applied as the control frequency.
