Operation of single-phase direct AC-AC converter using single phase matrix converter / Zahirrudin Idris

In these work basic investigations are carried out on the operation of a proposed single-phase direct AC-AC converter using single phase matrix converter (SPMC) topology without the use of a DC-link. Three different categories of operation, namely; a) AC-AC converter, b) frequency changer (increased...
