Tóm tắt

This paper deals with the AC voltage transformation circuits, which contain matrix or matrix-reactance PWM AC fine conditioners. These circuits can be treated as PWM AC/AC semiconductor transformers. In this paper the review of single-phase topologies are presented. The review covers both nonisolated and isolated ones as well as single or two-quadrant structure. Furthermore there are shown the averaged models, their four terminal chain parameters and some exemplary applications are outlined of presented AC voltage transformation circuits as well.
