The Precision Factor

Power Factor Correction Calculator

Power Factor Correction is becoming a concern in the electronics industry. Power factor is the ratio of the real power to apparent power. Power factor can vary between 0 and 1, and can be either inductive (lagging power factor, pointing up) or capacitive (leading, pointing down). In order to reduce a capacitive (or leading) power factor, an inductor is added to make the power factor equal 1. The whole purpose of making the power factor equal to one is to make the circuit look purely resistive (apparent power equal to real power).

Precision, Inc. has developed PL Product, a user-driven software used to characterize PFC inductors over a range of output power. Based upon desired circuit operating parameters, design engineers can calculate the PL Product required for their application and correlate it to the PL Curves of various PFC inductors. This simplifies the design process by making inductor selection easier, but also allows circuit and PFC inductor characteristics to be realized under various operating conditions.

Use the below PL Product Calculator to assist in choosing the correct Power Factor Inductor Design for your circuit. Input the parameters from your circuitry into the boxes to find the closest standard Precision, Inc PFC Inductor for your circuit. If this Inductor does not match your needs, contact Precision, Inc. for a custom PFC Inductor.
