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 /spl alpha//spl beta//spl gamma/ 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 /spl alpha//spl beta//spl gamma/ representation.
