Three dimensional space vector modulation for four-leg inverters using natural coordinates

Thanks to the use of natural coordinates (abc coordinates), the proposed modulation algorithm is much simpler and intuitive than using αβγ representation, reducing the complexity of modulation algorithm and the computational load associated to it. The application chosen, the 4-wire 4-leg inverter, is employed only as an example of how easy the modulation results using this notation instead of classical αβγ representation.
