Comparison study between pulse width modulation and space vector applied to three phase voltage source inverter / Nurul Aini Nadhirah Mohd Mahfodz
This paper describes the operation of three phase voltage source inverter (VSI) and how it operates. Since VSI can be applied in several method, thus the results will show comparison between pulse width modulation (PWM) and space vector modulation (SVM) method applied to three-phase VSI.

| Summary: | This paper describes the operation of three phase voltage source inverter (VSI) and how it operates. Since VSI can be applied in several method, thus the results will show comparison between pulse width modulation (PWM) and space vector modulation (SVM) method applied to three-phase VSI. The hardware implementation, simulation and programming had been applied in this project with MATLAB software for simulation result and MPLAB software used for programming of PIC 16F78A. The results obtained from hardware were compared with simulation results. There are two circuits used to run the hardware which are controller circuit and voltage source inverter circuit. SVM and PWM are used to control switching of MOSFET according to firing sequence applied. The comparison will show the better method apply for voltage inverter by considering total harmonic distortion (THD) which is SVM since it produce low THD. |
