Abstract: 
A novel topology for ripple-free input current circuit is put forward in the paper. Compared to traditional EMI(electromagnetic interference) filter consisting of choke and capacitor, the ripple-free topology can reduce the converter's ripple current with the use of smaller component. The new ripple-free topology proposed in this paper does not need elaborate adjustment of the coupling coefficient as required by conventional ripple-free techniques, and is ripple voltage cancellation or isolation mode, which can attenuate the ripple further if the line impedance is considered. The theoretical prediction is confirmed by experimental results.
