What is PFC controller?
PFC (power factor correction; also known as power factor controller) is a feature included in some computer and other power supply boxes that reduces the amount of reactive power generated by a computer. If the power factor is above 0.8, the device is using power efficiently.
How does a PFC boost converter work?
The boost PFC converter uses a switching element to force the input AC current to be sinusoidal and in phase with the input voltage. The example used in this article showed that significant improvement to the power quality of a power supply can be obtained by using a boost PFC converter.
What does PFC stand for?
Private first class
Private first class (PFC) is a military rank held by junior enlisted personnel in some countries’ armed forces.
How does power factor correction ( PFC ) work?
Home > Glossary > Power Factor Correction (PFC) The power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses. These pulses can be smoothed out by using active or passive techniques.
What does PFC stand for in computer category?
PFC (power factor correction or power factor controller) PFC (power factor correction; also known as power factor controller) is a feature included in some computer and other power supply boxes that reduces the amount of reactive power generated by a computer.
What can PFC be used for other industries?
PFC (power factor correction or power factor controller) PFC is not used solely for computer power supplies. In other industries, PFC equipment is used to reduce the reactive power produced by fluorescent and high bay lighting, arc furnaces, induction welders, and equipment that uses electrical motors.
What is the purpose of an active PFC controller?
The fundamental purpose of an active PFC controller is to make the load drawn from the mains appear resistive. Obviously, the downstream load is non-resistive in most cases (usually a constant-power load like a DC/DC converter) .
