Asma, Naik R. L., Jangamshetti Suresh H.

Abstract: Space Vector Pulse Width Modulation (SVPWM) method is an advanced computational intensive PWM algorithm for voltage source converter. Among various PWM techniques, SVPWM is most preferred technique because of higher DC bus utilization and ease in implementation. Traditionally processors like Microprocessors, Microcontrollers, DSP and dsPICs are used to implement SVPWM. However these processors are having limitations like moderate processing, complex implementation and higher switching losses. To overcome these aspects ATmega microcontroller is proposed for implementing SVPWM. The paper presents a review of different processors like DSP, dsPIC and ATmega further implementation of SVPWM using ATmega328P has been presented. The results shows that the space vector PWM waveforms generated are symmetric with respect to the middle of each PWM period. It has been concluded that ATmega microcontroller is the suitable processor for implementing SVPWM technique.
