Hexagon based algorithm for Space Vector Modulation on multilevel voltage source inverters

A simple algorithm has been developed to control small and large multilevel inverters using Space Vector Modulation. It looks for a suitable hexagon near the reference voltage rather than the usual three nearest vectors. Then, switching vectors and their duty cycles are computed using straightforward equations, independent of the number of levels and easy to use in digital microprocessors. Several simulations have validated this method, finding that these duty cycles are exactly the same than others, computed using more complex methods.
