Abstract:

A new class of impedance networks is proposed in this paper. The proposed coupled-inductors-based impedance cells, called the series and the tapped switched-coupled-inductors, are employed within the (quasi) switched boost networks. The achieved impedance networks based on the proposed cells offer very high conversion gains with less-than-unity turn ratios (n <; 1), which simplifies the realization of the magnetic element and at the same time reduces the number and size of passive components. The high boosting capability is achieved with small shoot-through durations that bring some additional advantages, such as low ratings of switching devices. The circuit analysis and operation concepts as well as a design procedure for the components of the proposed impedance networks are presented. Theoretical achievements are confirmed through experiments on a 220 W dc-dc converter laboratory setup.
