| Summary: | With rapid development in power semiconductor devices, the usage of power electronic systems has
expanded to new and wide application range that include residential, commercial, aerospace and many
others. Power electronic interfaces such as switch mode power supplies have proved to be superior over
traditional linear power supplies. However, their non-linear behavior puts a question mark on their high
efficiency. The current drawn by the switch mode power supplies from the line is distorted resulting in a
high Total Harmonic Distortion and low Power Factor. Power Factor, the ratio between the real or
average power and the apparent power forms a very essential parameter in power system. It is indicative
of how effectively the real power of the system has been utilized. With the stringent requirements of
power quality, power factor correction has been an active research topic in power electronics, and
significant efforts have been made on the developments of the power factor correction
converters. This project aims to develop a circuit for power factor correction using active filtering
approach by implementing boost converters arranged in parallel. It shall be based on an optimized
power sharing strategy to improve the current quality and at the same time reduce the switching
losses. The simulation result shows that the power factor was improved when the power factor
corrector circuit added to the inverter and the power factor corrector circuit switching with
proportional-integral-derivative controller shows better power factor then using pulse width
modulation switching mode. |
