Abstract

A modified boost power converter with an extra LC branch paralleled with the active switch has been proved to have the same ldquo;voltage follower rdquo; property as the conventional boost power converter operating in discontinuous inductor current mode (DICM) In this paper, a new modified boost power converter which has an extra LC branch paralleled with the passive switch is proposed. It is proved that the new modified boost topology has continuous input inductor current when it operates in the DICM. By using coupled inductor techniques, the input inductor current can be made ripple free when it operates in the DICM. It is proved that the new modified power converter can retain the ldquo;voltage follower rdquo; property with any coupling coefficient value. A comparison between the new modified boost power converter, the existing modified boost power converter, conventional boost, the Cuk and Sepic power converters used in power factor correction is presented. Several advantages are found in the two proposed boost topologies. The differences between the two proposed boost topologies are also presented. The predicted theory is verified experimentally
