Exploring the Theoretical Limit of Voltage Transfer Ratio of Matrix Converter Under the Constraint of Rotating Vector

The rotating vectors of a matrix converter are uniquely featured by producing zero common-mode voltage, and control methods using them have the advantage of inherently achieving common-mode voltage minimization. However, the existing knowledge of their low voltage transfer ratio (VTR) has made it di...
