  • Publication number: 20060125449
    Abstract: A duty cycle controller apparatus for producing a duty cycle signal for controlling switching of switches of a battery charger having an AC input for receiving power and an output for supplying power to charge a battery in response to switching of the switches, while maintaining a high power factor at the AC input. The duty cycle controller apparatus includes a current command signal generator having a plurality of signal inputs for receiving a plurality of signals representing a plurality of operating conditions of the charger, a plurality of current command outputs and a processor operably configured to generate a plurality of current command signals at the current command outputs in response to respective sets of operating conditions.

  • Publication number: 20060126241
    Abstract: A system having input terminals including line and neutral terminals for receiving AC power from a first AC source and having output terminals including output line and neutral terminals for receiving AC power from output terminals of a second AC source and for supplying AC power to a load, has a transfer switch configurable to connect the input terminals to the output terminals or to isolate the input terminals from the output terminals. When the transfer switch is configured to isolate the output terminals from the input terminals, the second AC source is caused to cease supplying power to the output terminals when after phase shifting the voltage produced by the second source the voltage at the input terminals is in-phase with that voltage.

When the transfer switch is configured to isolate the output terminals from the input terminals, the second AC source is caused to cease supplying power to the output terminals when a first voltage signal and an input current signal indicate the voltage and the input current satisfy a first set of criteria.
