  • Device and system for controlling parallel power sources coupled to a load
    Patent number: 7739525
    Abstract: A device and system for controlling current from plural parallel power sources having inrush current hot-swapping capabilities to a load are disclosed. The current controlling device includes a load line for delivering currents from the outputs of the power sources; a current sensor for measuring the load current; and a common sense element for adjusting the load current levels.

  • Holdover circuit for a power converter using a bi-directional switching regulator
    Patent number: 7646186
    Abstract: A holdover circuit is configured with a holdover capacitor, preferably an aluminum electrolytic capacitor, to provide uninterruptible operation for an electrical load operable over a limited range of input voltage during brief power interruptions. The holdover circuit includes a switching regulator configured with two active switches that are controlled with complementary duty cycles to charge and discharge the holdover capacitor at a voltage higher than the voltage of the load. The controller for the switching regulator may be configured to regulate the voltage of the holdover capacitor at a voltage proportional to the load voltage or at a constant voltage. The controller for the switching regulator is configured to operate in different modes during normal powered operation and during holdover.
