摘要： A system may include an uninterruptible power supply (UPS) configured to provide power to a load via a bypass feed path coupled to a first power source or via an inverter feed path coupled to a second power source. The UPS may include a controller configured to switch between providing power to the load via the bypass feed path and the inverter feed path based at least in part on a real-time calculation of an amount of voltage distortion present on a voltage signal input to the load via the bypass path. As such, the controller may be configured to provide power to the load via the inverter feed path when the amount of voltage distortion is greater than a limit.

摘要： A control system for parallel connected inverter legs energized by a power source and configured for servicing a load is disclosed. The invention facilitates the number of running inverter legs to adaptively react to changes in the load by dynamically switching various inverter legs “on” or “off” in response to variations in load demand, while continuing magnetization of an output transformer connected with an “off” inverter leg via a back-feed from another output transformer of an “on” inverter leg, greatly improving the dynamic response to load changes. This design enables a fast reaction to load changes with “off” inverter legs transitioning to on-line operation instantaneously.

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.

摘要： Systems and methods are provided for controlling an uninterruptible power supply (UPS) to transition between three- or higher-level operation and two-level operation in a neutral-point-clamped (NPC) inverter. In an example, a UPS system includes an NPC inverter and a controller. The NPC inverter may supply power to a load. The controller may control the inverter to operate in a three-level mode or higher when the load is substantially balanced and to operate in a two-level mode when the load is substantially unbalanced.
