To generate the required reference vector than triangle comparison based PWM techniques for three-level inverters the Space vector based PWM strategies contain broader choice of switching sequences. This Space Vector based PWM technique involves in various steps. These steps are computationally exhaustive. (SVPWM) has been used in three phase inverter control system. The center-aligned PWM is the most effective way for the MCU implementation of the SVPWM, because it can easily generate the center aligned PWM. For the multilevel inverters for generation of the signal of space vector pulse width modulation (SVPWM), this concept brings out the method. The inverter leg switching times are generated by this algorithm and the middle vector switching times are centered, in a sampled interval. The proposed algorithm does not require any sector identification. And it reduces the computational time as a result. The adjacent voltage space vectors are forming the small triangles. It is called sectors. Multilevel converters can meet the increasing demand of power ratings and power quality associated with reduced harmonic distortion and lower electromagnetic interference. To optimize switching waveforms, space vector pulse-width modulation algorithms offer great flexibility among them. And they are well suited for digital implementation.
