Abstract :
A simplified space-vector pulse width modulation (SVPWM) scheme for any N-level inverter is presented. The method involves the conversion of space vector diagram of NN-level inverter to that of a 2-level inverter. 60° coordinate system is used to represent space vectors instead of using cartesian coordinate system. In 60° coordinate system only integer coordinates are involved. So the computational complexity is reduced. The proposed scheme is experimentally verified for a three level inverter realised by cascading two 2-level inverters.
