    摘要: A passive power factor correction (PFC) circuit is disclosed. It converts an AC input voltage into at least one DC output voltage. A diode bridge and a diode pair rectify the AC input voltage and provide first and second rectified voltages, respectively. A resistor applies the second rectified voltage to a first capacitor that stores the first voltage. A diode applies the first voltage to an inductor. The inductor applies the first rectified voltage to an output capacitor that stores the DC output voltage. The passive PFC circuit is intended to expand commonly used full-wave bridge rectifier and following storage capacitor. It can replace an input circuit, including low pass filter, in many applications even if improved power factor is not required. The passive PFC specifically targets size of the inductor while avoiding any switching, and maintaining power factor that challenges active PFC circuits. Early prototypes reached power factor of 0.99 while driving a 100 W load.

    摘要: A harmonic input current reduction and power factor correction circuit for three phase, power supplies. The circuit includes passive elements including a series inductance and capacitor connected between each AC line of a three phase voltage source, and each input phase of the uncorrected power supply. The inductance and capacitor are designed and chosen to meet linearity and volt ampere requirements to achieve total harmonic current levels of less than 10%, and power factors greater than 0.98. This is achieved with less than 1% loss in line operating input voltage range and overall efficiency of greater than 99.5%. Further, the dynamic response of a circuit to power supply load transient demands is limited in voltage overshoot or undershoot effects.
