On the Implementation of a 3D Space Vector Modulation Algorithm

This paper reports on the development of an efficient C-script implementation of a 3D Space Vector Modulation (3DSVM) algorithm for a Three Phase Four-Leg Voltage Source Inverter. The duty cycles calculations are performed in the three dimensional stationary frame αβγ. The algorithm takes advantage of the finite-set of space-vectors in order to avoid calculating a matrix inversion. The algorithm is implemented in a C-script and tested by simulation in PLECS.
