Abstract
The analysis of the theory and realization on reducing EMI with jitter frequency modulation technology is presented. EMI tests and comparison are accomplished respectively on a 60 W switch mode power supply controlled by Top249 integrated with frequency jittering function and a 2 KW high-power switch mode power supply controlled by TL494. The results prove that this technique has a remarkable effect on decrease EMI noise level
