Description: Variable speed drives with Pulse Width Modulation are increasingly applied in many new industrial
applications for more efficient performance. Recently, developments in power electronics and semiconductor
technology have lead to widespread use of power electronic converters in the power electronic systems. A number of
Pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply from a three-phase
voltage source inverter. Among the different PWM techniques proposed for voltage fed inverters, the sinusoidal PWM
technique has been popularly accepted. But there is an increasing trend of using space vector PWM (SVPWM) because
of their easier digital realization, reduced harmonics, reduced switching losses and better dc bus utilization. This paper
focuses on step by step development of SVPWM implemented on a PMBLDC motor. Simulation results are obtained
using MATLAB/Simulink environment for effectiveness of the stud Platform: |
