Abstract
A power factor correction apparatus is for correcting a power factor of transmission lines. The power factor correction apparatus includes a switch, a compensator, a detecting apparatus, a voltage processing circuit, a voltage comparison unit, and a time-delay unit. The switch is electrically connected to the transmission lines. The compensator is electrically connected to the switch for compensating the power factor. The detecting apparatus is electrically connected to the transmission lines for detecting voltages transmitted in the transmission lines. The voltage processing circuit electrically is connected to the detecting apparatus and the switch. The voltage processing circuit includes a voltage comparison unit and a time-delay unit. The voltage comparison unit is electrically connected to the detecting apparatus for comparing the voltages with each other to generate a voltage. The time-delay unit is electrically connected to the voltage comparison unit and the switch delaying the voltage.
