  • Apparatus and Methods for Powering Remote Devices Under Dynamic Source and Load Conditions
    Publication number: 20090091310
    Abstract: Power provided to a remote network component is regulated. A monitoring circuit estimates a DC input voltage that is received from a central network supply. A control circuit compares the DC input voltage to a threshold DC voltage value to determine if the DC input voltage exceeds the threshold DC voltage value. A voltage conversion circuit converts the DC input voltage to a DC output voltage that is provided at an output voltage conductor and that is less than the threshold DC voltage value, if the DC input voltage exceeds the threshold DC voltage value. A bypass circuit bypass the voltage conversion circuit and transmit the DC input voltage to the output voltage conductor as the DC output voltage if the DC input voltage is less than the threshold DC voltage value.
