450W Power Factor Controller with Universal Input Voltage Range

This power factor controller accept voltage from 90 to 268 Vac,  that’s why we call it power factor controller with universal input, since any standards of mains supply  in almost any country would fall within that range. This power factor controller is capable of handling up to 450W load. Here is the schematic diagram of the power factor controller circuit: […]

Active Power Factor Correction Circuit

Active power factor correction stabilize the electrical demand of a device to give the best power factor characteristic of many types of loads.  To meet power factor regulation, a low cost solution should be designed. In many application, the need of high DC voltage is usually implemented by a direct rectification of the AC line followed by bulk capacitor filtering. […]
