Abstract :
Chaotic spectrum-spread technology is advantageous in improving EMC of power converters, but it increases ripple of output voltage. This paper puts forward a method for calculating output voltage´ s ripple of chaotic power converter. Simulation shows, ripple of output voltage increases with the increase of chaotic modulation coefficient. For suppressing the ripple of output voltage, we suggest adding an active filter to the output circuit of power converter, the active filter has small size and low cost, and its effect to the dynamic characteristic of power converter is small.
