Abstract: A system and method to increase solar system efficiency via a novel symmetric direct current regulation (SDCR) system to maximize useable solar power and optimize storage of energy in battery pack systems. The SDCR system maximizes delivery of generated solar power to the battery storage, utility grid or local building loads. The SDCR system comprises a plurality of photovoltaic arrays whose output voltage is mapped to the operational voltage of a LiFePO4 battery storage system and a grid-tied inverter. Efficiency is increased by approximately 30% via (a) the elimination of in-line charge controllers for stepping down power from the PV array to the battery pack, and (b) the elimination of boost controllers for stepping up power to the requirements of the inverter. Thus, the SDCR system is able to support low-loss symmetric delivery of electrical power to both the battery storage pack and the inverter.

Abstract: A communications system is described providing the ability to intelligently deliver electrical power from a first power source or from a second power source to a branch circuit in a facility, such as a home. Communications between a Smart Load Center (SLC) controller and the appliances is provided via a combination of signals sent over the electrical wiring and signals sent over the air. In particular, the signals over the electrical wiring serve to identify to which branch circuit the appliance is connected. The signals over the air support the communications between the appliances and the SLC controller, and may be part of a larger Internet-of-Things ecosystem dedicated to facilities automation services.

Abstract: A control unit of a power conversion device calculates a current target value and a voltage target value for a DC/AC converter on the basis of an output current target value, to control the DC/AC converter, and calculates a current target value for the DC/DC converter on the basis of the current target value and the voltage target value, and a voltage target value for the DC/DC converter, to control the DC/DC converter, thereby controlling output of an AC power. The control unit selects, as the voltage target value for the DC/DC converter, a greatest value at a present time, from among a DC voltage value of the DC power supply, an absolute value of a voltage target value for an AC side of the DC/AC converter, and a DC voltage lower limit value which is a predetermined value smaller than a peak value of the absolute value.

Abstract: An electrical power distribution system includes an electrical power router with input ports and output ports and distributes an electrical signal received on one of the input ports to one of output ports. An electrical input adapter coupled to one of the input ports and further to couple to an electrical power source receives and convert an electrical signal input from the electrical power source to the electrical signal distributed by the power router. An electrical output adapter coupled to one of the output ports and further to couple to an electrical power load receives and converts the electrical signal distributed by the power router from the one of the output ports to an electrical signal output to the electrical power load. A controller coupled to the electrical input adapter, the electrical output adapter, and the electrical power router, controls transmission of the electrical signal from the electrical input adapter to the electrical output adapter through the electrical power router.

Abstract: A system comprises a smart hybrid solar panel that employs a self-powered adaptive temperature control. Active temperature regulation may be implemented using a heat pump such as thermoelectric (TE) cooling modules and a switching circuit with variable duty cycle that periodically diverts the photovoltaic solar cell's output to the heat pump. A control system may algorithmically adjust the switching duty cycle to maximize the net power output of the panel based on a variety of sensory inputs and/or algorithms. The variety of sensory inputs may include weather forecast information, internal panel temperature, ambient air temperature, panel output voltage and current and humidity. The photovoltaic solar cells and heat pump are mechanically integrated.

Abstract: The disclosed dispersed power supply system includes a power conditioner configured to control output of a power supply apparatus, a current sensor, another power conditioner configured to control output of another power supply apparatus and another current sensor, and when a forward power flow threshold for preventing a reverse power flow of the power conditioner is lower than that of another power conditioner, the power conditioner controls the output of the power supply apparatus to adjust the forward power flow that is higher than the forward power flow threshold to the forward power flow threshold, and then, if the forward power flow is higher than the forward power flow threshold when another power conditioner controls the output of another power supply apparatus based on another forward power flow threshold, increases the forward power flow threshold.
