Abstract
Series Z-source network, an expansion of the popular concept of Z-source dc link, was originally proposed for boosting the output voltage of power electronic inverters. In this paper, that idea is extended onto a three-phase indirect matrix converter. The converter is based on the ultra-sparse matrix topology characterized by the minimum number of semiconductor switches. The series Z-source network is placed between the three-switch input rectifier stage and the six-switch output inverter stage in either the positive or negative rail. A brief shoot-through state produces the voltage boost. The inrush current and Z-source capacitor's voltage stress are reduced. An optimal pulse width modulation technique was developed for higher boosting capability of the converter and minimization of switching losses. © 2012 IEEE.
