    摘要: The present disclosure generally relates to automatic smart jump start battery packs (broadly, reserve power supply systems) for machinery. In exemplary embodiments, a battery pack is configured (e.g., includes a microcontroller, etc.) to automatically detect when machinery (e.g., a water pumping system, etc.) needs a jump start from the battery pack. For example, a microcontroller (e.g., broadly, a controller, etc.) within the battery pack may be configured to determine when the machinery's main battery does not have a sufficient charge to operate an electric starter motor of the machinery, e.g., when a main battery signal from a voltage sensor falls below a predetermined level, etc.

    摘要: A power supply unit (PSU) dynamically limits total recovery current. The PSU includes at least a power input, a power output, a historic maximum power draw memory, an update logic, and a recovery current limiting logic. Some implementations include a latest power measurement register, an hourly max power register, and a rolling max register, and controlling firmware. The update logic monitors a power level. The update logic updates the historic maximum power draw memory to match the monitored level. After a power interruption, the recovery current permitted to flow into the PSU is limited based on the historic usage. The recovery current may be limited in a constant, stepped, or ramped manner. The PSU may also provide power distribution. Multiple PSUs may be treated as a group, allowing an individual PSU to exceed its historic usage while the group's recovery currents are limited to the sum of historic usage levels.

    摘要: An uninterruptable power supply (UPS) system for providing power to a load coupled to a utility power source is provided. The UPS system includes a doubly-fed induction generator (DFIG), a rechargeable energy storage system, a first inverter, and a controller in communication with the DFIG and the first inverter. The DFIG includes a stator and a rotor coupled to the load. The stator and rotor are magnetically coupled together. The DFIG generates an auxiliary power output. The first inverter is coupled between the rotor and the rechargeable energy storage system. The controller detects a power disturbance associated with the utility power source and controls the first inverter to provide an excitation input to the rotor in response to the power disturbance. The DFIG provides the auxiliary power output to the load based on the excitation input.

    摘要: A system includes a first power source and a variable neutral impedance circuit configured to vary a neutral impedance of the first power source based on presence and absence of a parallel coupling of the first power source with a second power source. The variable neutral impedance circuit may be configured to reduce a neutral current of the first power source when the first power source is operating in parallel with the second power source. The variable neutral impedance circuit may include an impedance coupled in series with the first power source, a bypass switch configured to bypass the impedance and a control circuit configured to control the bypass switch. The impedance may include a resistor.

    摘要: Several embodiments include a power network system for a data center. The power network system can provide high voltage direct current (HVDC) power to server racks or any IT load racks type. For example, a HVDC converter circuit can provide the HVDC power by converting AC power. The power network system can also include multiple redundant power systems (e.g., a genset, a capacitive backup power system, a turbine-based generator system, or any combination thereof). The capacitive backup power system can provide HVDC power when the AC power fails and/or when the HVDC converter circuit can no longer provide sufficient power. The genset can be turned ON after the AC power fails. However, the genset may not provide stable power until sometime thereafter. Hence, the air turbine-based generator system can provide nearly-instant backup power once turned ON and provide supplemental energy in combination with the capacitive backup power system to smooth out transitions of power sources.
