  • Parasitic power supply and sensor apparatus including a power supply
    Patent number: 9088209
    Abstract: A parasitic power supply derives power from its proximity to an electrical power conductor. The power supply includes a transformer having a coil disposed on a core structured to be disposed parallel to the power conductor. The coil has a voltage induced by current flowing in the power conductor. A voltage regulating circuit cooperates with the transformer and includes a capacitor having a voltage, a charge switch structured to charge the capacitor from the coil voltage, a bootstrap circuit structured to enable the charge switch to charge the capacitor when the capacitor voltage is below a first predetermined value, a charge controller structured to enable the charge switch to charge the capacitor when the capacitor voltage is below a second predetermined value, and a voltage regulator powered by the capacitor voltage.
