—This paper presents a new analytical method for the generalized study of a cluster of single-stage power-factor correc-tors (S 2 PFCs). Due to this generalized approach, new topologies have been obtained, and the study of other known topologies has been simplified. The new analytical method simplifies the design of S 2 PFCs by making it possible to compare(More)
Passive current sharing in multiphase converters, where resistive losses are not dominant, is a quite complex goal. In this work, input impedance of active clamp boost converters is used like a lossless passive equalization in multistage high power factor rectifier. This technique allows the design of high power converters by and easy parallel association(More)
Power stages can be connected in parallel to increase the output power. Whenever, it requires current sharing among phases, to optimize the design. A method to achieve the desired current sharing is with equalizing resistors, what it means power losses, or connecting converters with high impedance. In this work has been studied that input impedance of(More)
The high output impedance of active clamp buck and boost converters have been tested as a good method to achieve steady state current sharing among several power stages working in parallel. Nevertheless, dynamic current sharing among paralleled or interleaved phases must be ensured. In this work, the current share dynamic performance of this lossless(More)
—Passive current sharing in multiphase converters, where resistive losses are not dominant, is a quite complex goal. In this paper, an averaged model of an active clamp buck converter was obtained. It has been checked that this topology presents high output impedance. This property is used like a lossless passive equalization. The principle of operation,(More)
—This paper presents a new methodological approach to teaching power electronics converter experiments. This approach is based on a reconfigurable hardware–software platform for use in converter experiments in a basic power electronics course. This course is an optional subject, and, therefore, the experiments need to motivate the students. The platform is(More)
