Patent ID: 8912842

Claim:
A device for stabilizing an effective value of an output current of a converter, wherein the device comprises: an input to receive an input voltage x of the converter, a memory in which a first set of polynomial coefficients a, b, c; k j is stored, a processor that is coupled to the input and the memory and is set up so as to determine a current correction y as a polynomial function with the stored first set of polynomial coefficients a, b, c; k j as a function of the received input voltage x, wherein the first set of polynomial coefficients a, b, c; k j is determined as a polynomial function of an effective setpoint of the output current using a predetermined second set of polynomial coefficients g a , h a , i a , g b , h b , i b , g c , h c , i c ; p ij , and a power stage that is coupled to the processor to receive the current correction y and set up to modify the effective value of the output current as a function of the current correction y.
