Power factor correction (PFC) is gaining popularity as a way to make the power grid more energy efficient. But optimizing PFC circuits for a particular application has been difficult — until now. The PL Product is a user driven software for Design Engineers that is designed to identify and select PFC inductors over a range of output power more quickly.
Given designers input, regarding the desired circuit operating parameters, the PL Product calculates the product factor required for the application and correlates it to Pl Product curves. These interactive Pl Product curves and the resulting computations, quickly help Design Engineers select a PFC inductor to meet their specific requirements
One reason why PFC circuits can be difficult to design is that engineers must fully understand the PFC inductor’s operating characteristics and its effect on the PFC circuit as design criteria changes. The PL Product makes it easier for circuit designers to understand the relationship and trade-offs among circuit parameters and the inductor.
The PL Product also gives Precision — a leading manufacturer of inductors and other magnetic components — a more effective way of relating the performance of PFC inductors. Seeing how circuit and PFC inductor characteristics behave under various operating conditions makes a selection of the right inductor much easier for engineers.
The PL Product was designed by Precision, Inc.. Mr. Welly Chou; a Precision Sr. Design Engineer, was selected for presentation of a paper on the derivation of the PL Product and PFC inductor selection. The paper was presented at the 25th Annual IEEE Applied Power Electronics Conference (APEC) this past February, 2010.
