| Abstract |
In this paper two input current modulation strategies for
matrix converters are experimentally analyzed under two
different supply conditions: sinusoidal unbalanced voltages
and nonsinusoidal balanced voltages. Both strategies use the
Space Vector Modulation (SVM) technique in order to control
the matrix converter accordingly to the input and output
constraints. Strategy A modulates the input currents
keeping the corresponding space vector in phase with the
input voltage vector. Strategy B operates in order to keep
the input current vector in phase with the positive sequence
fundamental component of the input voltage vector. A comparison
between the two strategies is made in terms of reduction
of the input current disturbances due to voltage non
idealities present on the grid. It is concluded that a dynamic
current modulation strategy, independent of the voltage disturbances
such as Strategy B, is more effective for the reduction
of the RMS value of input current disturbances. The
validity of the theoretical investigation and the effectiveness
of the current modulation strategy have been confirmed by
experimental tests carried out on a matrix converter prototype. |
