Resumen:
The boost topology with ripple cancellation network allows input and output current ripple attenuation, which means the suppression of the input filter and a high reduction of the output filter. However, to achieve the ripple cancellation, the complexity and the number of components of the converter increase compared with the conventional boost. A detailed analysis has been developed to specify the advantages and drawbacks of this topology. This paper presents the averaged model that derives the complex transfer function of the topology. The theoretical transfer function has been obtained. Due to the complexity of the seventh order transfer function obtained, a simplified second order transfer function has been calculated in order to simplify control design calculations. A comparison between the analyzed topology and a conventional boost in terms of weight and losses has been carried out. To estimate input and output current ripple calculation, it is proposed the use of the ripple theorem, which allows.
