This project offers ongoing power factor correction without needing to manually adjust the capacitive bank. A PFC controller handles power factor correction and limits peak current for any type of switch-mode power converter, like buck, boost, or buck-boost designs, without needing to directly measure the inductor current. The PFC control method uses a piecewise-polynomial analogue computer to calculate the on-times for power transistors. It uses separate polynomial transfer functions for power-factor control and peak current limiting, based on inputs that represent line input voltage (VLN), load output voltage (VLD), and long-term current demand (VCD). A conduction cycle starts when the rate of change in the inductor current reaches zero, detected using an auxiliary winding on the current storage inductor. The cycle ends after the calculated on-time, which is used for either power-factor control or peak-current limiting. Reactive power charges on your electricity bill are applied to companies that don't show clear energy efficiency. This charge is listed on your electricity bill. Reactive power charges can be reduced significantly by using Power Factor Correction Capacitors, which is a well-known way to lower electrical loads, save energy, improve plant efficiency, and cut electricity costs. It's not always needed to reach a power factor of 1. A cost-effective solution can be achieved by raising the power factor to more than 0.95. This project uses a regulated 5V, 750mA power supply. A 7805 three-terminal voltage regulator is used for voltage regulation. A bridge-type full-wave rectifier is used to convert the AC output from the secondary side of a 230/12V step-down transformer.
