This Dataset, as a Matlab script, shows input voltages vectors and output voltage reference vector for improved control of input power factor in Multiphase Conventional Matrix Converters (MCMC) using the transfer function of the load angle. Compared to the direct space--vector modulation techniques, the proposed solution can rely on the load parameters and obtain the greater value of an input displacement angle in a certain range of voltage transfer ratio and the load power factor.

This animation is a supplement to the article 'A new approach to the PWM modulation for the double, square–type, conventional matrix converters supplying loads with open-end winding.' This is an animation of the four basic modulation schemes of PWM modulation for the Conventional Matrix Converter using the rotated vector concept based on the Hilbert transform, which can be performed by DSOGI filter.

In this simulation, the DC voltage of the matrix converter is derived using a three-phase linear load as a sample. It shows that the voltage used by the three inverters and the average over the switching period are always the same. It also shows that when the load is constant, the DC current of the inverter is also constant.

In this simulation, the phase difference of the signals a, b, and c in the paper is changed to 0 in 0.1 seconds from the state where the phase is 90 degrees different from the input voltage. The input current phase is the same as the above signal. Since the output voltage gradually increases, it can be seen that the DC voltage of the matrix converter increases as the phases of a, b, and c become closer to the input voltage phase. Strictly speaking, it is proportional to cosθ as described in the paper.
