  • Patent number: 11210747
    Abstract: The present disclosure provides a distributed and anonymous approach to demand response of an electricity system. The approach conceptualizes energy consumption and production of distributed-energy resources (DERs) via discrete energy packets that are coordinated by a cyber computing entity that grants or denies energy packet requests from the DERs. The approach leverages a condition of a DER, which is particularly useful for (1) thermostatically-controlled loads, (2) non-thermostatic conditionally-controlled loads, and (3) bi-directional distributed energy storage systems. In a first aspect of the present approach, each DER independently requests the authority to switch on for a fixed amount of time (i.e., packet duration). The coordinator determines whether to grant or deny each request based electric grid and/or energy or power market conditions. In a second aspect, bi-directional DERs, such as distributed-energy storage systems (DESSs) are further able to request to supply energy to the grid.

  • Patent number: 11005373
    Abstract: A switching power supply apparatus includes a switching device and a switching power supply control circuit for converting an AC source voltage to a DC voltage. A comparison circuit in the switching power supply control circuit produces an H-level output signal when its non-inverted input voltage exceeds a voltage value during each off-state period of the switching device. A delay circuit outputs a pulse signal after a predetermined delay time from detecting the H-level signal. This pulse signal indicates detection of a bottom point of drain voltage of the switching device. Since the output of the delay circuit is directly connected to the set input terminal S of a flip-flop, the switching device is surely turned on, without bottom skip, upon detection of the bottom point of its drain voltage.

  • Patent number: 10777967
    Abstract: A current driver is disclosed which allows very short pulses at high currents to be generated for high power laser diodes. The parasitic inductance of the laser diode limits the speed at which the laser diode may be turned on and off. A high voltage is used to charge this inductance rapidly and maximize the rise time. The fall time is shortened by allowing a similar high voltage to be generated at turnoff without damage to the laser diode or switching components. A portion of the energy stored in the parasitic inductance may recovered to reduce drain on the power source, and to improve overall efficiency. The anode of the laser may be switched to ground at the end of a pulse.

  • Patent number: 10763661
    Abstract: A reverse current protection circuit for a switch circuit includes a reverse current control circuit and an enable/disable circuit coupled to the reverse current control circuit. The reverse current control circuit is coupled to an input terminal and an output terminal of the switch circuit, and disconnects the output terminal of the switch circuit from the input terminal of the switch circuit when an output voltage of the switch circuit is higher than a first predetermined voltage. The enable/disable circuit disables the reverse current control circuit for a first predetermined time period when the output voltage of the switch circuit becomes lower than the first predetermined voltage after being higher than the first predetermined voltage, and enables the reverse current control circuit after the first predetermined time period.

  • Patent number: 10756651
    Abstract: Provided is a power generating element and a power generating device capable of using vibration energy not used for power generation in the past. The power generating element includes a displacement member, a fixed member, and an elastic deformation body. An electret material layer is formed on a surface of one of the displacement member and the fixed member. A counter electrode layer opposed to the electret material layer is formed on the other surface. When vibration energy is given to the power generating element, the displacement member is displaced with respect to the fixed member such that an inter-layer distance between the electret material layer and the counter electrode layer fluctuates according to deformation of the elastic deformation body.

  • Patent number: 10715036
    Abstract: In a power converter, a switching network having switches that operate at a common frequency and duty cycle interconnects circuit elements. These circuit elements include capacitors that are in a capacitor network and a magnetic filter. When connected to the capacitors by a switch from the switching network, the magnetic filter imposes a constraint upon inter-capacitor charge transfer between the capacitors to maintain the filter's second terminal at a voltage. The switching network transitions between states. These states include a first state, a second state, and a third state. In both the first state and the third state, the first magnetic-filter terminal couples to the capacitor network. In the second state, which occurs between the first and third state, the switches ground the first magnetic-filter terminal.

  • Patent number: 10697432
    Abstract: A method for operating at least one energy storage device of a renewable energy facility connected to a power grid in multiple operational modes includes providing an operational threshold for the renewable energy facility. Further, the method includes comparing an operational parameter of the renewable energy facility with respect to the operational threshold. The method also includes controlling the renewable energy facility based on the comparison. As such, when the operational parameter is below the operational threshold, the controller communicates to the energy storage device(s) to increase its state of charge (SOC) in anticipation of the renewable energy facility transitioning from producing power to consuming power.

  • Patent number: 10686484
    Abstract: A switching network and associated method for operating within a transceiver are disclosed. The switching network has a timing control circuit that offsets the time at which a through switch and a shunt switch transition between on and off states. The output of the timing control circuit is an inverted and delayed version of a control signal applied to the input of the timing control circuit. Controlling the timing of the shunt switch provides a means to safely discharge any accumulated charge within the capacitance Cgs between the gate and source of transistors included within the through switch.
