Abstract:
In remote areas various security forces and law enforcing agencies need to use modem tools and
communication equipments for national interest and security. Also, in hilly areas and tactical
points of the country, the military forces need to use modem communication equipments and
electronics. All these need to investigate alternative supply sources and delivery mechanisms for
those systems. Community participation in off-grid electrification projects, using renewable
energy sources, is a fast -growing method of increasing access to electricity. Storage power
supplies, such as, batteries and fuel cells have been used in situations where electric power from
the grid is unavailable; in remote area power systems, earth orbiting satellites or space probes,
consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water
pumping applications. Presently, solar arrays are used to supply communication equipments in
remote areas.
Users in remote areas use DC equipment and systems suitable for storage power or alternative
power sources. Historically, solar cells have been used in situations where electric power from
the grid is unavailable. Recently solar cells are particularly used in assemblies of solar modules
(photovoltaic arrays) connected to the electricity grid through an inverter, often in combination
with a net metering arrangement. In this research work proposed equipments that are built to
accept DC power supplies of solar system at 12V or 24V DC. In such applications common
communication or telecom apparatus of 120V AC 60/50 Hz or 230V AC 60/50 Hz cannot be
used. If a power supply unit using such a system may be designed and fabricated to provide
conventional AC voltage at 50/60 Hz, then commercially available communication equipments
may be used in remote installations without customised modules. This paper describes a new
strategy for converting the solar power for use in a commercial telecom/communication set using
a Resonant Inverter and a Cuk Converter. The main objective is to investigate the solar electric
system. The comprehensive system consists of PV array, Cuk converter, resonant inverter,
battery and battery charger. The Solar array, Cuk converter and resonant inverter have been
widely studied. A useful discussion has also been included.
