Power factor correction substation is used to improve the kraft correction factor, computer switching kraft supply is a capacitive input circuit, the phase difference between the current and voltage will cause the loss of exchange power. At this time, it is necessary for power factor correction substation to increase power factor. In order to improve the power correction factor of the power supply, the state forces power supply manufacturers to pass power factor correction substation. In fact, this point in Intel’s power supply design specifications have also been forced to provide.
