    Abstract: A transfer switch selectively couples at least two power sources to a load. The load may be a home, business, or vehicle. A current transformer is coupled to the output of the transfer switch and generates a load measurement signal that is proportional to the current or power output from the transfer switch. A controller receives the load measurement signal and a switch setting describing the operation of the switch. The controller generates data for a status message for display based on the load measurement signal and the switch setting. The status message may describe the power consumption of the load or indicate when an error has occurred.

  • Patent number: 10455722
    Abstract: An external power supply containment unit includes a chassis configured to mount to a structure external to a rack. The external power supply containment unit further includes one or more discrete power supplies mounted in the chassis and one or more electrical connectors that are configured to couple and decouple with a power distribution system of a rack positioned adjacent to the external power supply containment unit. The electrical connectors are configured such that racks of electrical devices, such as computers, can be replaced while the external power supply containment unit remains mounted to the external structure. Additionally, discrete power supply units included in the external power supply containment unit may be re-used to provide power to electrical devices included in a replacement rack when a rack of electrical devices coupled with the external power supply containment unit is replaced.

  • Patent number: 10439392
    Abstract: A serial acquisition of multiple power sources via one or more multiplexers which is circulated in many corridors of a multi-port system with a resonant engine. A controller manages multiplexer/switches connecting a first plurality of DC power sources and an auxiliary DC power source to a circulator. A multiplexer/switch revolves each source of power to inverters for DC-AC conversion. Reciprocity of power sharing and management of signal routing between input power sources can be performed to maintain discrete operation between the input/output power sources and individual power inverters for precise load power delivery. Regenerative power from a motor load can be directed to “recharge” an input power source. The resonant engine applied to each power source provides a constant conduit of energy during off-operation/cycles.

  • Patent number: 10439402
    Abstract: An adaptive power system for powering a dynamically changing load may include an energy storage device, a bi-directional current source, and compensation circuitry. The bi-directional current source may be electrically connected between the energy storage device and a power distribution bus of a power distribution system. Further, the bi-directional current source is configured to receive a compensation value and, based on the compensation value, maintain a constant power level on the power distribution bus by delivering current to the power distribution bus from the energy storage device or absorbing current from the power distribution bus for storage in the energy storage device. The compensation circuitry may be configured to generate the compensation value. An expected average current value for the dynamically changing load and a power distribution bus current value may be used to generate the compensation value for maintaining the constant power level on the power distribution bus.

  • Patent number: 10418851
    Abstract: A control device controls an uninterruptible power supply device such that a transition is made to an inverter power supply mode when a power source abnormality detecting unit detects a power failure of an AC power source in a case where a commercial power supply mode is selected. The power source abnormality detecting unit computes an estimated value of the maximum value of AC input voltage, based on detected values of the instantaneous value and the phase of AC input voltage supplied to an input terminal. The power source abnormality detecting unit is configured to store temporal transition of the maximum value when the AC power source undergoes a simulated power failure and determine a power failure of the AC power source, based on comparison between temporal transition of the estimated value of the maximum value and the stored temporal transition of the maximum value during power failure.
