Abstract

This paper presents a new continuous carrier-based pulse width modulation (CPWM) method to control three-phase direct matrix converter (DMC). This technique is based on the equivalent indirect scheme, which models the converter as two independent stages to perform rectification and inversion processes. With this representation, two CPWM methods of the rectification process are proposed. In the inversion stage, the well-known CPWM methods of the standard voltage source inverter (VSI) have been applied. With these techniques, a voltage transfer ratio (VTR) of 0.937 has been achieved in the linear modulation mode. This value is higher than the present attainable value of 0.866. The proposed technique has been implemented using a laboratory setup. Measured results showed the validity of the given analysis.
