Power factor correction (PFC) is the set of mechanisms built into a power supplycircuitto raise the power factor (PF). PFC is commonly incorporated into computer power supplies to increase their PF. A circuit's PF is the ratio of real power toapparent power. The higher the PF, the mor...
The active PFC methods are preferred for power supplies of over 100W. This method provides a more efficient correction, is lighter and less bulky. A basic active PFC circuit consists of a control circuit that measures the input voltage and current and then adjusts the switching time and duty ...

What is FCFS? FCFS is "First Come First Served" FCFS Definition / FCFS Means The definition of FCFS is "First Come First Served" The Meaning of FCFS FCFS means "First Come First Served" So now you know - FCFS means "First Come First Served" - don't thank us.YW!
Some non-isolated converters, including the boost converter used in a PFC circuit, only converts in one direction, up or down. In the case of a boost converter, it only outputs a voltage higher than the input voltage. If an ac-dc power supply with power factor correction is operated with...

Displacement occurs when the circuits voltage and current sine waves are out of phase of one another. Another way to look at this would be to look at the power equationP=IV. If the peak voltage value is not at the peak current value in time, then the circuit is not achieving the maxim...
