Abstract:
This paper presents a road map for the design and
development of sustainable hybrid High Brightness Light
Emitting Diode (HB LED) illumination systems with
maximum power point tracking (MPPT). The proposed
hybrid system design presents the foundation for future
sustainable high efficiency illumination systems. The
system design presented in this paper individually
controls an array of HB LEDs. Each HB LED operates
in a different mode defined by the user. Photovoltaic
(PV) panels-based systems are used as the primary source
of energy in this system while the electric grid is used as
the backup source that supplies power to the HB LEDs
only when the power of the PV system is not sufficient to
supply all the system HB LEDs and the PV system
batteries are depleted below the minimum level set in the
system design. A matlab/ Simulink model is proposed for
studying the system behaviors and operation modes.
