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.

Abstract: The present disclosure is directed to systems and methods involving a power converter and various control schemes in which the power converter is able to monitor and intelligently manage various operational scenarios such as startup and shutdown of a fuel cell, load sharing among two or more available power sources, and exporting excess power from one available power source to a different power source, as well as transient step up and step down load situations requiring an immediate increase or decrease in the power being provided to a load. Various hierarchical power converter control schemes are also disclosed for addressing different types of operational scenarios, which enable the power converter to centrally manage some or all of the available power sources to optimally use all of the power supplying resources available to it to best meet the requirements of the load.
