Abstract
Dynamic characterization of the coupled-inductor boost DC-DC converter is presented. Operating of the converter in both continuous conduction mode (CCM) and discontinuous continuous conduction mode (DCM) are studied. A state variable equivalent to the inductor core magnetic flux is defined to avoid the problem with using the discontinuous inductor current as a state variable. Dynamic model of the converter under peak-current control is also developed. Control to output transfer functions are calculated for all the dynamic models and are validated by experimental measurements. A comparison to the conventional boost converter is providedKeywords
