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 m...
Edit. A power factor correction inductor can be added to a linear load (sine wave), which has a leading power factor, to increase the power factor. This type of power factor is known as a displacement power factor because the current is displaced relative...
This is where power factor correction capacitors come in — they generate reactive power and therefore reduce the amount of reactive power the motor requires from the utility. The end result is a higher power factor. Power factor correction capacitors can be either fixed or automatically switched. ...
Essentially, power factor is a measurement of how effectively electrical power is being used. A higher power factor represents a more effective use of electrical power. Power Factor Correction on a switching power supply controls the timing and wave shape of the input current drawn to maintain ...
Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is. Power Factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA)...
A higher power factor represents a more effective use of electrical power. Power Factor Correction on a switching power supply controls the timing and wave shape of the input current drawn to maintain the current waveform approximately in phase with and of the same shape as the line voltage. ...

General Description OSG90R1K2xF use advanced GreenMOSTM technology to provide low RDS(ON), low gate charge, fast switching and excellent avalanche characteristics. This device is suitable for active power factor correction and switching mode power supply ap...
Power supplies are theoretically simple devices, and conceptually, evaluating them is quite straightforward: Do they put out the correct voltage and current? Today's modern power supplies are anything but simple. Most have sophisticated features like input power factor correction circuitry and output ...
Generally, a modular power converter consists of a mains-connected front end and some number of independent DC modules. The front end itself houses the EMC filtering, power factor correction and the isolation transformer. Power is transferred from the front end to each of the DC modules which ...
