What is it about?
Design a generalized switching states, different switching patterns and implement a space vector pulse width modulation technique for any multilevel inverter that reduces the extra switching commutations that may occurs during edge of the sector or triangle in the space vector diagrams of any multilevel inverter.

Why is it important?
The expressions of the switching states is general, different switching sequence is also general depends upon the number of switching commutations. However the technique does not require to calculate all the switching states for simplicity. Only the most desired and a few redundant states are required to calculate.
Perspectives
The paper is suitable for designing a space vector PWM technique for a multilevel inverter of any configuration with large number of levels without overloading the system as only selected number of switching states are required to calculate. Further the different switching patterns can be designed by using the technique that may reduce the extra switching commutations if any.
