Integration of optical wireless communications (OWC) within switched-mode power supplies (SMPS) / Although visible light communication(VLC) systems can provide high density links
for use with IoT devices, an energy efficient, high rate method of designing a VLC
transmitter is still unclear. Present designs for transmitters such as the bias-T, designs
with switch manipulation, and interleaved converters are not commercially viable due
to costly and complex designs that sacrifice energy efficiency for data rate. A design
allowing for efficient, high rate communications, while maintaining a low cost would
allow for widespread adoption of this technology.
In this thesis, a novel approach of integrating power converters and VLC systems is
explored by replacing commutating diodes with LEDs. By leveraging switched-mode
power supply(SMPS) structures, the power dissipated within the converter may be
harnessed and used for communications. The result is a simple and energy efficient
solution capable of high rate links.
Simulation and experimental results demonstrate buck and boost SMPS topologies
that simultaneously increase energy efficiency and provide communications at SMPS
switching rate without increasing component count. / Thesis / Master of Applied Science (MASc)
