Elimination of the waveform distortions in the voltage-source-converter type matrix converter
- McGill Univ., Montreal, Quebec (Canada). Dept. of Electrical Engineering
The recently reported voltage-source-converter type matrix converter offers advantages in terms of employing the well-known and proven technology of the 3-phase voltage-source converters, bypassing the switching difficulties associated with the bidirectional switches in the conventional 9-switch matrix converter topology, and reduction in the conduction losses. The new matrix converter topology is capable of establishing the dual condition of Unity Displacement Power Factor on the utility-side and Field Vector Control on the motor load-side. However, because of the special structure of the transformation matrix and the presence of dc components in the side-2 voltages, the branch currents on side-1 and the ac voltages on side-2 contain some unwanted components resulting in additional losses and waveform distortions. This paper addresses the above problem and proposes a novel technique for the elimination of the unwanted components. Experimental results are used to verify the correctness of the theoretical expectations.
