ABSTRACT:
A method is provided for compensating an output signal of an electronic device having an input end electrically connected to a feedback device and an output end electrically connected to a load. This method includes steps of (a) measuring a standard voltage V.sub.o of the load, (b) determining an input voltage V.sub.i and an input current I.sub.i of the electronic device, and (c) generating a feedback signal based on said input voltage V.sub.i. The method further includes steps of (d) determining a maximum current I.sub.max and a minimum current I.sub.min of the feedback signal passing through the feedback device, (e) defining an estimated output current I.sub.o of the electronic device based on the maximum current I.sub.max and the minimum current I.sub.min, and (f) compensating the output signal of the electronic device according to a compensating factor d determined by the standard voltage V.sub.o, the input voltage V.sub.i, the input current I.sub.i, and the estimated output current I.sub.o, of the electronic device. The estimated output current I.sub.o is calculated according to the maximum current I.sub.max and the minimum current I.sub.min by a first equation of I.sub.o =I.sub.max +kI.sub.min where k is a constant.
