  • Patent number: 10981465
    Abstract: A system includes energy modules that output power to an energy management bus based on load demands. An energy module includes energy cells enclosed within a module housing that provide power to the energy management bus and a driving system attached to the module housing that transports the energy module. The energy module includes a local controller that controls power output from the energy cells to the energy management bus, engages a self-driving mode in response to receiving a disconnection signal from a central controller, and controls movement of the energy module in the self-driving mode to a predetermined location via the driving system. The central controller receives a current module status from the energy modules and controls a configuration of the energy modules providing power to the energy management bus based on the current module status.

  • Patent number: 10964469
    Abstract: Core-coil devices operate by electromagnetic induction and include inductors, transformers, and electromagnets. Cooled core-coil devices include a magnetic core having a channel through it, and a coil wound around the core. Cooled core-coil devices additionally include a coolant loop that carries ferrofluid coolant through the channel and forms a loop with the channel that extends outside the core. Ferrofluid coolant circulates in the loop without a pump due to a thermo-magnetic response to the device's thermal and magnetic field gradients and thereby cools the core while simultaneously adding to the device's inductance.

  • Patent number: 10782716
    Abstract: The present disclosure intends to simplify the wiring structure of a switching circuit included in a power conversion apparatus. A feedback signal acquisitor acquires a power supply feedback signal corresponding to electric power transmitted from a power supply switching unit to a load switching unit, via coupling conductive elements, from the power supply switching unit. Alternatively, the feedback signal acquisitor acquires a load feedback signal corresponding to the electric power, via coupling conductive elements, from the load switching unit. A command signal generator generates a power supply switching command signal and a load switching command signal. A command signal transmitter transmits the power supply switching command signal to the power supply switching unit via the coupling conductive elements, and transmits the load switching command signal to the load switching unit via the coupling conductive elements.

  • Patent number: 10381497
    Abstract: An apparatus and method for optical-power-transfer (OPT). A light source converts electrical energy into light, and the light is transmitted from the active layer of the light source directly to the active layers of a series of photovoltaic (PV) devices without first passing through a conduction layer of the PV device. Thus, absorption in the conduction layer is avoided, and the efficiency of the OPT system is improved. The PV devices are configured to each generate equal current, and the PV devices are electrically connected in series. PV devices are arranged in series with light first propagating through PV devices closer to the light source, and farther PV devices having a longer propagation length, such that the light absorbed and current generated by each PV device is equal to the other PV devices. In one implementation, the PV devices are configured in a laser cavity with the light source.
