Implementation of SVPWM Based Three Phase Inverter Using 8 Bit Microcontroller
In this paper, the authors describe the digital implementation of Space Vector Pulse Width Modulation (SVPWM) technique using 8-bit microcontroller for three-phase inverter. For control of IM number of Pulse Width Modulation (PWM) schemes is used to variable voltage and frequency supply. The most commonly used PWM schemes for three phase Voltage Source Inverters (VSIs) are Sinusoidal PWM (SPWM) and SVPWM. There is an increasing trend of using SVPWM because of it reduces harmonic content in voltage, increases fundamental output voltage by 15% and smooth control of IM.
