Abstract: A power supply system includes an energy storage device electrically connected to a power grid, a power distribution assembly electrically connected to a load, and a power generation device electrically connected to the power distribution assembly. The energy storage device and the power grid are configured to supply electric power having a first voltage range to the power distribution assembly, which in turn, is configured to supply electric power having a second voltage range less than the first voltage range to the load. The energy storage device and the power generation device each are configured to at least temporarily supply a flow of electric power to the power distribution assembly when electric power from the power grid is interrupted such that a substantially uninterrupted flow of electric power is supplied to the load.

Abstract: Electrical systems for providing uninterruptible power to a critical load. One electrical system includes a ring bus, multiple power blocks including one or more generators electrically coupled to the ring bus, and uninterruptible power supplies (UPSs) electrically coupled to the ring bus. In some aspects, the electrical system includes a UPS switchgear electrically coupled between the ring bus and the UPSs. In other aspects, the UPSs are electrically coupled together in parallel. Another electrical system includes a utility switchgear, UPS blocks electrically coupled together in parallel and electrically coupled to the utility switchgear via transformers, low voltage (LV) power blocks electrically coupled to the UPS blocks, and medium voltage (MV) switchgear electrically coupled to the UPS blocks via transformers. Each of the LV power blocks include one or more generators.

Abstract: Modular dual power sources and corresponding systems include a common hybrid energy storage system, a high frequency DC-DC converter coupled between the common hybrid energy storage system, and an ultra-capacitor module for starting up a generator, and a two-level inverter coupled to the common hybrid energy storage system to provide power in case of an interruption in power supplied by a utility supply. The hybrid energy storage system includes an ultra-capacitor module and a battery module. A fast charger is coupled to the hybrid energy storage system to quickly charge the ultra-capacitor module and the battery module, which, in turn, charge the ultra-capacitor module for starting up a generator via a high frequency DC-DC converter. High frequency transformers are used to magnetically isolate electrical noise of the generator and UPS functions and operate independently. The modular dual power sources can be connected in parallel to provide large MW output power.
