摘要： 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.

摘要： The present disclosure relates to a system for controlling power walk-in for an uninterruptible power supply (UPS) being switched to receive AC power from an AC generator. The system may have a control system and a power walk-in (PWI) subsystem. The PWI subsystem may be controlled in part by the control system. The PWI subsystem may be configured to control at least one of an input current or an input power of an AC signal being provided by an AC generator during a power walk-in operation to attempt to maintain a minimum frequency of the AC signal from the AC generator during the power walk-in operation.

摘要： The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to help control powering a load when an AC mains power source is not available to provide power to the load. The system has a power converter forming an uninterruptible power supply, and includes a controller configured to control operation of the power converter. A supplemental battery subsystem is included which is in communication with the power converter for supplying DC power to the power converter. The controller monitors the application of power from the utility proxy to the load and uses the DC power supplied by the supplemental battery subsystem, when needed, to supplement the generation of power by the power converter, to thus assist the power converter in powering the load along with the power being provided by the utility proxy.

摘要： An uninterruptible power supply (UPS) system with stranded power recovery has a plurality of UPS modules with one or more of the UPS modules usable to provide stranded power to a recovered power bus. When a UPS module is used to provide stranded power to the recovered power bus, the AC/AC converter associated with that UPS module provides AC power that is synchronized with AC power being provided to the recovered power bus by each of the other AC/AC converters that are providing AC power. In this manner all of the AC/AC converters that are providing AC power to the recovered power bus have the same voltage, the same frequency and are in phase.
