Claim 3:
4. The method according to claim 3, wherein said at least one threshold value (S1, S2, S3, S4) also comprises at least a first lower threshold value (S3) and a second lower threshold value (S4), said step of regulating or interrupting (E) said supply voltage (V) and/or current (I) and/or frequency (F) involving:
reducing the value of said supply voltage (V) and/or current (I) and/or frequency (F) if said control parameter (R) assumes a value equal to or greater than said first lower threshold value (S3);
zeroing the value of said supply voltage (V) and/or current (I) and/or frequency (F) if said control parameter (R) assumes a value equal to or less than said second lower threshold value (S4).
