Abstract
<div class="section abstract"><div class="htmlview paragraph">This article presents the development of a solution that uses solar energy to
power refrigerated semi-trailers. The solution employs photovoltaic cells on the
surfaces of the semi-trailer, combined with a battery pack, which take advantage
of a significant area with solar exposure and generate sufficient electric power
to supply the refrigeration unit responsible for controlling the temperature
inside the climate-controlled chamber. In addition to providing energy for the
refrigeration unit, the solar system can be integrated with the auxiliary
traction system used in some semi-trailers, functioning as a range extender for
the battery. To achieve the main objectives of this development, studies were
conducted to evaluate solar radiation through simulations considering different
regions of Brazil. A hardware system was also developed for energy management
and to drive the refrigeration unit, combining a high-power drive system
composed of filters, DC/DC converters, and transformers to match the voltage
levels of the systems, with a microprocessed circuit for functional logic
control. As a result, a system capable of operating the refrigeration unit using
solar energy was obtained, which can reduce diesel consumption by up to 1800
liters per year.</div></div>
