  • Patent number: 10998730
    Abstract: An adaptive solar power battery storage system is disclosed to capture alternative energy for use when desired, regardless of power generating circuit topology (AC or DC). The adaptive solar power battery storage system may be connected directly to solar panel cells (for DC-type solar panels) or to micro-inverters (for AC-type solar panels). The adaptive battery storage system can be configured to accept power from both energy sources simultaneously (AC or DC), or each individually. The adaptive solar power battery storage system may enable the operation of AC-type solar panels in the absence of utility power, which is ordinarily used to supply a reference signal to the micro-inverters, by converting stored DC battery power to AC to generate an emulated reference signal. The system may monitor the utility power and adjust the emulated reference signal to track the utility power to enable a safe transfer back to utility power once restored.

  • Patent number: 10291064
    Abstract: A DC power system distributes low voltage (12/24 V) power through a central DC panel to multiple DC loads, such as LED lighting, and to multiple dedicated DC outlets, into which computers, televisions and cell phones can be directly plugged without using an AC-to-DC rectifier. The central DC panel is supplied with DC power (24-36 V) from a central bi-directional inverter, which converts AC-to-DC and DC-to-AC. The inverter also receives DC power generated by non-grid local alternative energy sources, such as wind turbines and photovoltaic solar cells. The local alternative DC power is processed through a voltage regulator in the inverter, which renders the voltage and power uniform enough for use by DC loads. When the local non-grid DC power exceeds the demands of DC loads, it is routed through the inverter to charge a storage battery, which in turn supplies DC power to the DC panel when the non-grid DC power sources are offline.

  • Publication number: 20140132169
    Abstract: The present invention relates to a power converter architecture and its operation principle that supplies an electric load with a controlled direct voltage from both a local direct current electricity source as well as an alternating current (AC) mains with maximum power conversion efficiency. For the case that the local electricity source can not provide enough electricity to the local load it is additionally supplied with electricity from the AC mains. In other case electricity is also feed into the AC grid when a local source can provide more electricity than needed to supply local loads.

  • Publication number: 20140117755
    Abstract: A power system for supplying direct current (DC) voltage to a load requiring same includes a main power supply outputting a first alternating current (AC) power, an auxiliary power supply outputting a first DC power directly, and a bidirectional power factor correction device. When the bidirectional power factor correction determines that the first DC power is more than a rate power of the load, the auxiliary power supply outputs only a first part of the first DC power to the load, and outputs a second part to the bidirectional power factor correction. The bidirectional power factor correction converts the second part into a second DC power, and redirects the second DC power into the main power supply. The first part of the first DC power output allowed into the load equals to the rated power of the load.

    Abstract: First power load apparatuses that use power from a power storage apparatus when a total power consumption amount of all of the plurality of power load apparatuses is greater than or equal to a threshold, and second power load apparatuses not included among the first power load apparatuses are included. A power gateway apparatus stops the supply of power from a power supply system to the first power load apparatuses and performs power supply from the power storage apparatus to the first power load apparatuses when a sum of a total power consumption amount of the second power load apparatuses and a total power consumption amount of the first power load apparatuses exceeds a threshold indicating a maximum value of the system power consumption amount. The power gateway apparatus supplies power from the power generation apparatus to the first power load apparatuses with priority to power from the power network.

  • Publication number: 20130093241
    Abstract: A dc energy store includes auxiliary systems operable in different modes, including self-supporting, island mode and normal modes. In the self-supporting mode a first controller uses a voltage demand signal indicative of desired ac voltage of an AC/DC power converter to control semiconductor power switching devices to achieve the desired level of ac voltage. The voltage demand signal is derived from comparing a voltage feedback signal and a second voltage demand signal preset to provide the desired ac voltage for the auxiliary systems. A second controller uses a current demand signal indicative of the desired dc link current to control the semiconductor power switching devices of a DC/DC power converter to achieve the desired level of dc link current. The current demand signal is derived from comparing a dc link voltage demand signal indicative of a desired dc link voltage and a dc link voltage feedback signal.
