A Novel Approach Towards Performance Analysis of Three Phase Two Level Inverter

For three phase two level inverters, a comparison between Space Vector Pulse Width Modulation (SVPWM) and Sinusoidal Pulse Width Modulation (SPWM) is done. Sine Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) are the most often used PWM techniques for three phase voltage source inverters. To run the motor at its rated speed, we are specifically using the SPWM and SVPWM techniques to enhance motor speed and improve performance. The excellent efficiency and minimal torque ripple of this vector control approach, together with improved system performance, make it suited for use in high performance motors. It has been found that switching occurs only once in SVPWM when moving from one state to another in a switching sequence, which results in lower switching loss. In contrast, multiple switching occurs in SPWM when moving from one state to another, which increases switching loss and lowers efficiency. SVPWM produces reduced Total Harmonic Distortion (THD), offers improved output quality, and more effectively utilizes DC bus voltage. The MATLAB/SIMULINK program is utilized to carry out the system analysis. In light of all the information we had gathered, we consequently came to the conclusion that the Space Vector PWM technique provides better comprehensive performance and efficiency when compared with the Sine PWM technique. However, due to the advantages of the SVPWM technique, it can be applied to solar-powered water pumping systems to increase their water pumping effectiveness.
