Pulse Width Modulation (PWM) Inverter for Control Applications

Abstract

Industrial automation point of view inverter plays a very important role in developing drives. The PWM is widely used for motion control with two level voltage source inverters to obtain a quality output voltage or a current waveform with minimum amount of ripple content that they require for high switching frequency along with various pulse width modulation (PWM) strategies. These two level inverters have drawn tremendous inverters for high voltage and high power applications. This paper has proposed for design and implementation of sinusoidal pulse width Modulation i.e SPWM and multilevel technique to decrease the harmonics. The design and development of multilevel techniques will carried out in Matlab / Simulink environment.
