Sinusoidal Pulse Width Modulation

This paper deals with theoretical and practical outlook related to implementation of a Digital signal processor (DSP) based on Sinusoidal Pulse Width Modulation (SPWM). For single phase inverter, sine wave is taken as reference signal and saw tooth is taken as carrier signal. It is developed by TMS320F28027 piccolo TM microcontroller with the help of simulink model. TI Texas instrument TMS320 is a blanket name for a series of DSP from Texas instrument. Through the TMS32010 processor which was faster in the DSP market and we use C2000 series microcontroller family with performance integrated peripherals designed for real – time control applications like motor drive control, industrial automation, solar and other renewable energy sources. The voltage source inverter is used in motor speed control and in solar, wind power grids. The system is verified by experimenting in simulation.

<p>The aim of this paper to presents a comparative analysis of Voltage Source Inverter using Sinusoidal Pulse Width Modulation Method, Third Harmonic Injection Pulse Width Modulation Method and Space Vector Pulse Width Modulation Two level inverter for Induction Motor.  In this paper we have designed the Simulink model of Inverter for different technique. An above technique is used to reduce the Total Harmonic Distortion (THD) on the AC side of the Inverter. The Simulink model is close loop. Results are analyzed using Fast Fourier Transformation (FFT) which is for analysis of the Total Harmonic Distortion. All simulation are performed in the MATLAB Simulink / Simulink environment of MATLAB.</p>

<span>Nowadays application of advanced power electronic technology enables producing an AC supply with a phase number higher than three-phase. Five-phase voltage source inverters (5ph-VSI) have been used in advanced power electronic drives to improve the reliability of the drive system and to boost the power capability of the converter as well as to their other inherent merits. This paper shows the mathematical analysis and simulation of the third harmonic injection pulse width modulation (THI-PWM) 5ph-VSI connected with inductive load in three scenarios i.e. star, Pentagon and pentacle. The presented THI-PWM technique for 5ph-VSI aims to increase the inverter fundamental voltage and hence to maximize the utilization of the DC bus without causing over-modulation. The simulation results are compared with typical sinusoidal pulse width modulation (SPWM) and the 10-step mode operation. The proposed scheme may be considered as a compromise case between the two reference cases;  as low harmonic components compared with 10-step mode operation and a high utilization factor compared with SPWM.</span>
