Scalar Modulation Strategy for Even-Phase-Output Matrix Converter

Abstract

Even phase drives in conjunction with multiphase matrix converter is a smart solution in connecting them to a three-phase source. It reduces the area required to install such drive due to the omission of bulky dc-link capacitor. This work concentrates on a mathematical solution to the equations that pertain to such a converter. Venturini method is taken as the basis of analysis. It is found that a mathematical solution does exist for an even-phase output converter only when the number of inputs is three. The theory is then supported with simulation as well as experimental results on $3 \times 6$ Matrix Converter.
