New Direct Ac-Ac Converters Using Switching Modules Solving the Commutation Problem

The focus of this paper is the study of direct AC-AC converters, beginning by buck, half-bridge, full-bridge and push-pull converters. From the basic converters we apply a simple methodology to make possible the use of switches in commercial configurations. After that, eight line conditioners were proposed supplying them on the line side or on the load side and the static gain transformer turns ratios were presented. It can be highlighted that some of the studied topologies are known in the literature and others are new. For one of the presented topologies, the design of a 3 kVA line conditioner is developed and experimental results are shown, certifying the correct operation of the drive strategy used
