Abstract:
A method for compensating an output signal of an electronic device, wherein said electronic device includes an input end electrically connected to a feedback device and an output end electrically connected to a load, comprising steps of:(a) defining an output voltage V.sub.o of said load;(b) determining an input voltage V.sub.i and an input current I.sub.i of said electronic device;(c) generating a feedback signal based on said input voltage V.sub.i ;(d) determining a maximum current I.sub.max and a minimum current I.sub.min of said feedback signal passing through said feedback device;(e) defining an estimated output signal I.sub.o of said electronic device based on said maximum current I.sub.max and said minimum current I.sub.min ; and(f) compensating said output signal of said electronic device according to a compensating factor d determined by a second equation ##EQU5## where V.sub.o is said output voltage, V.sub.i is said input voltage, I.sub.i is said input current, and I.sub.o is said estimated output signal of said electronic device.
