Pembangkit Sinyal SPWM Berbasis Arduino Uno

Jurnal Elektronika dan Otomasi Industri, 2022
Pemanfaatan energi listrik saat ini semakin berkembang pesat. Tetapi suatu saat pasti akan terjadi pemadaman listrik. Dalam dunia elektronika ada yang namanya inverter. Inverter adalah salah satu teknik untuk mendapatkan gelombang sinus murni dari konversi gelombang DC yaitu dengan memodulasi lebar sinyal pulsa gelombang DC tersebut. Teknik ini disebut

Generic SPWM technique for multilevel inverter

2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2013
Multilevel inverters generate stepped AC signals and thus overcome many of the limitations with the classical inverter circuit. Multilevel inverters use many number of switches and generate staircase type output through controlled switching of various switches. The sequence of switching and the duration of each step are very vital in minimizing the THD.

Analytical and comparative study of FHI-SPWM and SPWM control technique of Five-phase VSI

2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016
The modulating index (m) can be increased towards unity to increase the amplitude of fundamental voltage on the AC side of Five-phase Voltage Source Inverter having PWM control technique, without reaching over modulating area. For the star connected load, if the modulating index is considered as unity and inverter input DC voltage as V dc , then the ...

A Harmonic Reduction Scheme in SPWM

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
In this paper, a harmonic cancellation and sideband reduction method has been proposed with a view to improving efficiency in PWM signal processing. Mat Lab simulation has been used to optimize the sideband cancellation. Such cancellation of signals at unwanted frequencies has a substantial improvement in ac conversion efficiency.

SPWM based on programmable counter array

2011 Chinese Control and Decision Conference (CCDC), 2011
For the complexity of sinusoidal pulse width modulation, which have problems of slow response, trivial program and expensive realization device, programmable counter array is used in this paper to realize the SPWM with low cost in order to be used in the design of variable velocity variable frequency (VVVF).

Design and Implementation of SPWM Inverter

2019 International Conference on Computing, Communication, and Intelligent Systems (ICCCIS), 2019
This paper represents the fabrication and implementation of 50Hz SPWM inverter to convert the direct current to alternating current. Such as what can be continuous from a standard wall outlet. There are generally three types of the inverter in general purpose: modified sine wave, pure sine wave, and square wave. Considering the power output capability,

The designated harmonic suppression for SPWM

SPIE Proceedings, 2005
SPWM is a critical method used in asynchronous motor-driven area. But harmonic components of inverter output wave impair its application in motor speed control. A new mixed algorithm was proposed for SPWM, which was a designated harmonic suppression technology by way of improved regular sampling in low voltage and low frequency and harmonic ...

A Novel Multilevel Strategy in SPWM Design

2007 IEEE International Symposium on Industrial Electronics, 2007
In this paper, a novel multilevel strategy based on a signal slicing technique, and that employs phase-shifted carrier is presented for the design of SPWM inverters. The method relies on slicing the reference signal into various segments, carrier-modulates each segment independently, and multiplexes the carrier modulated slices in amplitudes.

Microcontroller based SPWM sampling using linear extrapolation

2017 International Conference on Inventive Systems and Control (ICISC), 2017
Implementing a Natural sampling technique of Sinusoidal Pulse Width Modulation in a pure microcontroller environment is difficult, considering the large processing time and controller intervention needed. Various optimized methods like symmetric regular sampling and asymmetric regular sampling are widely used in the industry, but are only roughly able ...
