Power Factor Correction Inductor
PC Mounted PFC Inductor, Toroidal Core, vertical mount
Precision works with its customers to optimize a Power Factor Correction (PFC) solution for any specific application. In many cases, audible noise is not a problem. For example, when the power supply is housed in an enclosure with forced air, PFC Inductor noise is not detectable and allows a lower cost solution. Also, if size is not the highest priority, there are many available options.
Precision can provide additional windings on the PFC Inductor to supply power for the PFC control circuitry. Using a voltage doubler circuit with this bias winding provides a semi-regulated output that is quite stable over the entire duty cycle range
