Abstract :
This paper presents a particular modulation technique based on the generalized scalar pulse width modulation strategy for matrix converters. The objective of this solution is producing identical duty cycles and double-sided switching pattern that the well-known space vector modulation technique without the high memory requirements and the complex trigonometric operations of the last. Both the space vector and the proposed modulation techniques are simulated in a permanent magnet synchronous machine fed by a matrix converter. Its performances are compared with respect to total harmonic distortion (THD), execution times, number of operations and memory requirements. A wide range of simulations are carried out to verify the advantages of the proposed modulation technique when compared with the space vector modulator.
