摘要： A method for controlling an uninterruptible power supply (UPS) for servicing a load is disclosed. The UPS has a bypass feed path operable in parallel with an inverter feed path, the bypass feed path being engagable with the load via a first switch, and the inverter feed path and being engagable with the load via a second switch. The method includes: generating a paralleling detection signal indicative of the bypass feed path operating to service the load in parallel with the inverter feed path; and, in response to the presence of the paralleling detection signal, modifying a control signal to an inverter such as to drive toward equalization the bypass current and the inverter current. As a result, and in response to the two paths operating to service the load in parallel, the method tends to cancel circulation current generated between the bypass feed path and the inverter feed path.

摘要： Systems, methods, and devices are provided for redundant control of parallel inverter installations. In one example, a parallel uninterruptible power supply (UPS) system may include several inverter feed paths and several UPS controllers. The inverter feed paths may supply double-conversion power to a load. The UPS controllers may be communicatively coupled to one another via at least two redundant data busses. The UPS controllers may operate in conjunction with one another to control the plurality of feed paths.

摘要： A control system for an uninterruptible power supply (UPS) for servicing a load is disclosed. The UPS includes a first feed path and a second feed path, where the first feed path is operable in parallel with the second feed path. The first feed path is engagable via a first switch to deliver a bypass current to the load. The second feed path includes a rectifier, an inverter responsive to a control signal and in electrical communication with the rectifier, and an output transformer in electrical communication with the inverter. The second feed path is engagable via a second switch to deliver an inverter current to the load. The control system is configured for facilitating magnetization of the transformer via a back-feed from the first feed path in response to the load being fed by the first feed path, the rectifier being off, and the inverter being off.
