Abstract :
This paper shows that by transforming both sides of the matrix power converter to the d-q-o frames of their respective frequencies, there is significant simplification in the existence matrix which enables the network of one side to be integrated to the other. Thus, it is possible to design for operation with field vector control on the motor side and unity displacement factor on the supply side. Laboratory experimental and digital simulation results are presented to substantiate the theory. The matrix power converter used in the test is based on three modules of voltage-source SPWM power converters to implement the 9 switches and it has the innovative feature that the SVC voltages (for displacement factor improvement) can be derived from the zero-sequence voltages
