Abstract
The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to control powering first and second loads when an AC mains power source is not available to provide power to the loads. The system uses an internal DC bus of a power converter to receive power from a utility proxy, and a DC/DC converter/charger of the power converter to receive power from a short term supplemental battery subsystem. The DC/DC converter/charger is used to supply a first AC output signal to power the first load. An AC/DC rectifier of the power converter uses the DC power from the utility proxy, supplied onto the internal bus, to generate a second AC output signal which is applied independently to the second load to power the second load fully independently of the first load.
