Each of the regulators is connected to a subset of serially connected power sources and so configured that if the voltage generated at the lowest tap is no longer sufficient for a stable supply to the local power consumption unit, the next higher regulator takes over, and the output voltage drops in small steps reflective of that takeover of the next higher tap. When the voltage generated across a subsection grows, a lower connected tap may take over again, producing a slightly higher output voltage for the local power consumption unit. The cutover steps are chosen such that the output voltage range matches the range given as the acceptable input range for the local power consumption unit.

  • Patent number: 10666047
    Abstract: A method includes the steps of providing a common DC bus to interconnect power elements to a DC distribution system using power converters. A first group of one or more of the elements (main element) is used to execute the primary function by automatically maintaining the DC bus voltage following a set point. The DC bus voltage set point is intentionally changed with slow dynamics according to a secondary function executed by the main element such that the average DC bus voltage regulated by the main element changes. A local logic is used on each of the power elements connected to the DC bus but different from the main element to modify their power generation or consumption as a result of changes in the measured average DC bus voltage such that they contribute to the fulfillment of the secondary level of control.

  • Patent number: 10367374
    Abstract: Electrical power is shared wirelessly among electrical power-sharing hubs in a wireless mesh network. Each electrical power-sharing hub includes one or more transmitters and receivers for wireless communications with other hubs and wireless power transfer technology to transmit or receive electrical power with other hubs. If electrical power at a respective electrical power-sharing hub is insufficient to power an electrical load on the hub, the hub wirelessly requests that a specific amount of electrical power be transmitted to it wirelessly from one or more neighboring electrical power-sharing hubs. At least one of the neighboring hubs may send a portion or all of the requested power. If the neighboring hubs do not have electrical power to share, a request for power is wirelessly transmitted to non-neighboring hubs, at least one of which may relay available electrical power wirelessly to the requesting hub via the wireless mesh network.

  • Patent number: 10333314
    Abstract: The disclosure relates to technology for providing power, voltage, and/or current from a combination of DC power sources, such as photovoltaic modules or DC batteries. One aspect includes a buck-boost optimizer having a number of inductorless buck stages and a boost stage. The buck-boost optimizer may be used within a power generation system. The combined output voltages of each of the buck stages may be input to the boost stage. The boost stage may have an inductor that may serve as an energy storage device to boost a voltage, as well as to filter a signal from the buck stages. Thus, the buck-boost optimizer may use a single inductor. Having a single inductor provides for a very efficient power generation system. Also, cost and size of components in the power generation system may be reduced.
