Abstract

In this paper, several types of direct frequency converters are described and compared. Mathematical models and results of simulation are presented. The first mentioned type of direct frequency converter is a three-to-single-phase double-zone converter. It is based on two series connected controlled voltage sources and can generate 49 possible output voltages. Different types of control can be used in such a converter; for example amplitude phase synthesis or pulse-width modulation. In the article, a three-phase to three-phase matrix converter is also described. Details of the pulse-width modulation and space-vector modulation schemes in such a converter are discussed. Implementation of the multi-level principle in the matrix converter is briefly analyzed. In the final part of the paper, a comparison of the above-mentioned converters is performed
