Abstract

Switched reluctance generator (SRG) has gained substantial research attention in recent years due to its mechanical robustness, high reliability, and low manufacturing cost when integrating renewable energy sources. To achieve reliable and timely information exchange in such microgrids, in this article, we propose a soft pulsewidth modulation approach, which injects an extra ripple at a particular frequency into the output voltage waveform of SRG, so as to realize synchronized transmission of signal and electric power. The signal transmission is achieved through a newly designed modulation/demodulation strategy. The efficacy of the overall dc microgrid in synchronized data transmission and energy conversion is verified through a set of dedicated experiments.
