Summary: | A power controller disclosed is for the use of a power converter with an inductive to regulate an output power source. The power controller has a PWM signal generator and a jitter inducer. The PWM signal generator controls a power switch to generate consecutive switching cycles. In each switching cycle the PWM signal generator controls a peak to regulate the output power source, and the peak is capable of representing a current flowing through the inductive device. The jitter inducer, connected to the PWM signal generator, is for altering the peak, so as to make a difference between two consecutive peaks. The difference has a sign and a magnitude. The jitter inducer makes the sign changed switching cycle by switching cycle. |
