Abstract

Abstract— Some measures of merit of an inverter system are the total harmonic distortion and the efficiency figures. On one hand, we have square wave and modified square wave inverters that have high efficiency and total harmonic distortion (THD) figures. On the other hand, there are the true sine wave inverters that have low THDs and relatively low efficiency figures at high output power levels. In this work, a five level waveform that can be synthesized efficiently was analysed for low distortion figures, and a THD figure of 1.25% was obtained. A microcontroller-based inverter circuit was designed to synthesize this waveform from a 12 volts d.c source. The microcontroller firmware and hardware were developed using MicroC® and Proteus® softwares respectively. The developed circuit generated a 50 Hz sinusoidal output waveform from a 12 volts battery source after filtering with an LC low pass filter.

The journal is currently an open access journal.

The articles receive both rigorous peer-review and expedited online publication.

The journal encourages young researchers to submit their unpublished papers.

The authors retain their article’s copyright.

The authors retain publishing rights without restrictions.

Thus, authors may use their own articles for the following non-commercial purposes without asking our permission (and subject only to acknowledging first publication in Journal of Communications Technology, Electronics and Computer Science and giving a full reference or web link, as appropriate).

Authors cannot submit a manuscript for publication to other journals simultaneously. It is a waste of valuable resources because editors and referees spent a great deal of time processing submitted manuscripts. It is also unethical to republish similar research articles (text/figures/tables) again because journals have limited page space and it most likely violates copyrights which have already been transferred to the first journal. Therefore, all journals require a signed author's copyright transfer agreement stating the originality of the research work submitted through a manuscript. As stated above that authors should submit original, new and unpublished research work to the journal. The ethical issues such as plagiarism, fraudulent and duplicate publication, violation of copyrights, authorship and conflict of interest are serious issues concerning ethical integrity when submitting a manuscript to a journal for publication.

The contents of papers are the sole responsibility of the authors, and publication shall not imply the concurrence of the Editors or Publisher.
