Fast Space vector Modulation without NTV Identification for Multilevel Inverters

This paper suggests a new space vector PWM method with very short processing time which does not need identification of nearest three vector (NTV) and duty ratio for each vector. The suggested PWM method makes mean value of phase voltage to be same as reference during every modulation period by use of a triangle in small hexagon on multilevel vector space. In this paper CAN serial communication protocol was used to implement the proposed method. This paper described the suggested modulation method can be successfully applied to the space vector modulation of multilevel inverter with CAN serial communication networks, for interface networks between the master and phase controller of inverter.
