DC-space vector abstraction in the virtual DC-link matrix converter theory

The working principle of the matrix converter has been described by many authors in various ways. Especially, the introduction of the virtual DC link concept was one of the most important milestones in the matrix converter theory. However, the mathematical description is not symmetrical in this case. That is why a new approach presented in this article strives to symmetrize the matrix converter voltage and current transfer functions. For this purpose, new term is defined: DC-space vector.
