| Abstract: | One of the concerns to put on the
energy efficiency is in relation to the system
power factor. From the view of industrial
practices, low power factor might cause
equipment failure and higher operation costs. This
paper proposes a conceptual design of
microcontroller-based self-adaptive power factor
corrector (PFC) circuit with the intention to be
used in the poor power factor (either linear or
nonlinear) loads applications. The design of this
auto-adjustable power factor corrector is to ensure
the entire power system always preserving almost
unity power factor and thus optimizing the current
consumption. Power factor value is initially
measured via microcontroller and it is then
compared with a pre-determined reference value.
The poor power factor of the entire system will
then be adjusted by the aid of the microcontroller
to as close as the pre-determined value as
possible. The proposed power factor corrector has
an adjustable sensitivity of 50 microseconds or 0.9
degree interval step setting. The conceptual design
of the power factor corrector circuit has gone
through a set of simulation tests using Computer
Aided Engineering (CAE) tool. The results
obtained are verified that the proposed PFC circuit
is capable to produce a reliable output and can be
further implemented in practical applications. |
