ABSTRACT:
An AC-to-DC converter and regulator normally receives power from an AC utility line and provides a stable DC output to a load, such as the power amplifier and transmitter of a cell site. The DC output, or a separate dedicated output from the converter, is used to charge a backup battery when AC power is available. If AC power is interrupted, the backup battery provides power to the load by way of a separate DC-to-DC differential converter. The battery is connected in parallel with the differential converter input, but in series with the differential converter output. Thus, the differential converter receives operating power from the battery, and outputs a voltage which is summed with the battery output to drive the load. A control circuit for the differential converter senses the voltage provided to the load, and supplies a signal to the differential converter to adjust its output as necessary to maintain the optimum aggregate output to the load.
