Abstract
This paper is dealing with the SVPWM inverter's operation. Then, after analyzing the space vector methodology, convenient detail equations are derived. The amplitude and frequency value of stator voltage are adjusted in this scheme to modulate the motor's speed. In addition, the SVPWM switching technique approach is an advanced and highly analytical modulation technique with many advantages over previous PWM modulations, including a lower harmonic content, efficient DC bus consumption. These numerous benefits have led to SVPWM finding more and more uses in motor control and power converters. In this research, the simulated analysis of the speed of the Permanent Magnet AC Motors is controlled by the voltage source inverters using the SVPWM switching techniques. It is commonly acknowledged that field Oriented Control for PMSM motor drives is frequently chosen for the highly efficient and better performance drive systems due to its distinct qualities including improved power factor and the low inertia and also it is superior in the power density. SVPWM method provides a greater DC voltage usage rate and less output waveform distortion when compared to commonly utilized sine-wave pulse width modulation (SPWM) approach. This report describes the procedure for using MATLAB to build the SVPWM modulation method and introduced SVPWM control technology for three-phase inverters. It also built a mathematical model of the circuit by creating a comprehensive closed-loop system for simulation that provides output waveforms. A model-based PI controller is designed for the FOC of the PMSM motor.
