Abstract: A method and battery charger for charging one or more batteries includes a pulse generator, a detector and a processor communicably coupled to the pulse generator and the detector. A recovery/discharge circuit is electrically connected to each battery, and one or more energy storage devices are electrically connected to each of the recovery/discharge circuits. A charging pulse group, which includes a positive pulse, a rest period and a negative pulse, is determined based on one or more battery parameters using the processor and the detector. The charging pulse group is generated using the pulse generator, and sequentially applied to each of the batteries. Energy is recovered from each of the one or more batteries using the recovery/discharge circuits during the negative pulse, and the energy is stored in the one or more energy storage devices. The battery parameters are monitored and the charging pulse group may be adjusted.

Abstract: A power conversion unit and method for efficient conversion of power for one or more variable loads are disclosed herein. Power having a first form is supplied to one or more power conversion units (PCUs) connected to the one or more variable loads. The PCUs are adapted to convert the power from the first form to other forms suitable for use by the components of the destination system. Based at least in part on a predicted load requirement of the variable load, the operation of the PCUs can be controlled to provide sufficient power to the one or more loads at the appropriate time while minimizing wasted power generation by deactivating any unnecessary PCUs during a decrease in power consumption or by activating PCUs during an increase in power consumption.

Abstract: A system and method for efficient distribution and conditioning of power to one or more variable loads are disclosed herein. Power having a first form is supplied to one or more power conversion units (PCUs) connected to the one or more variable loads. The PCUs are adapted to convert the power from the first form to other forms suitable for use by the components of the destination system. Additionally, a power control module is adapted to monitor the load requirements, both current and future, of the one or more variable loads. Based at least in part on the load requirements, the power control module controls the operation of the one or more PCUs to provide sufficient power to the one or more loads at the appropriate time while minimizing wasted power generation by deactivating any unnecessary PCUs.

Abstract: A power factor corrector includes a power stage that is electrically coupled to a controller. The controller is configured to receive a rectified AC voltage signal, summed with a reference level, and compare the received signal to a ramp signal. When the ramp signal exceeds the rectified AC voltage signal, the controller turns on a switch within the power stage. The switch is turned off synchronously with a periodically generated switch mode power supply drive signal.
