  • Power supply and method that maintains supply voltage in communications systems during a power supply interruption
    Patent number: 8247924
    Abstract: A power supply and associated method include a power supply converter having a power output and configured to provide a supply voltage through the power output to a communications device. A simplified boost circuit is connected to the power supply converter in parallel but isolated from the power supply converter's bulk input capacitance during normal operation. The boost circuit includes at least one power storage circuit and a charging circuit connected thereto and configured to charge and maintain the power storage circuit to a predetermined voltage and switch the power storage circuit into the power supply converter during an undervoltage condition to transfer the stored power from the power storage circuit to the power supply converter and maintain the supply voltage to the communications device connected thereto for a required hold-up time.

  • Adaptive power supply for telecommunications networks
    Patent number: 8212390
    Abstract: An adaptive power supply span powers devices used in telecommunications. It includes a power circuit and control circuit that receives power and sense signals therefrom and provides a control signal thereto and distinguishes between a first network interface load having a constant voltage input power requirement and a second network interface unit load having a constant current input power requirement. A voltage control circuit and current control circuit are interconnected together and connected to the power circuit. A control signal from the voltage control circuit and current control circuit extends to the power circuit. The control circuit maintains a fixed output voltage for constant voltage regulation for the first network interface unit load, if the output current remains below a threshold current.
