Matrix Converter
  A matrix converter is characterized by the ability of connecting any input phase to any output phase at any instant with an array of controlled semiconductor switches. This converter has been investigated for over two decades because it has many advantages over the conventional two-stage ac-dc-ac converter which needs bulky dc-link energy storage, electrolytic capacitor. By removing the bulky dc-link capacitor, the matrix converter can prolong its lifetime, can be realized compactly and has a high power density. In addition, since the input side and the output side of the converter is coupled directly by power semiconductor switches, the input power factor can be freely controlled by proper modulation, irrespective of the type of the load.
