Due to the three-phase-to-three-leg direct matrix converter (3 × 3 MC) cannot be achieved with unbalanced load, then the three-phase-to-four-leg direct matrix converter (3 × 4 MC) is introduced. A novel modulation strategy is proposed to ensure the capability of 3 × 4 MC with arbitrary loads, which is development by using fixed voltage vectors and one zero vector. Considering the harm of common-mode...
The matrix converter (MC) is a direct ac–ac power converter without an intermediate dc link. It has several attractive features, such as high power density, four-quadrant operation, and bidirectional power flow. However, the application of MCs in high-voltage and high-power systems is still limited by the device voltage levels. It is well known that the multilevel power converter technology can be...
The matrix converter (MC) is direct AC-AC power converter without an intermediate DC link which can offer a number of advantages, including unity input power factor, bidirectional power flow, an improved input current harmonic issue, capable of compact design and high power density without energy storage elements. Above advantages make the matrix converter suitable for aircraft, AC power supply unit...
The matrix converter (MC) is an array of controlled bidirectional semi-conductor switches that allows direct ac-ac conversion without an intermediate dc link. To extend its future application, multilevel matrix converter can be a proposed solution due to its merits in multilevel output, high voltage application, high power conversion, improved harmonics issue and less voltage step, etc. This paper...
