摘要： A distributed power harvesting system including multiple direct current (DC) power sources with respective DC outputs adapted for interconnection into an interconnected DC power source output. A converter includes input terminals adapted for coupling to the interconnected DC power source output. A circuit loop sets the voltage and current at the input terminals of the converter according to predetermined criteria. A power conversion portion converts the power received at the input terminals to an output power at the output terminals. A power supplier is coupled to the output terminals. The power supplier includes a control part for maintaining the input to the power supplier at a predetermined value. The control part maintains the input voltage and/or input current to the power supplier at a predetermined value.

摘要： The present invention relates to resiliency in photovoltaically produced power generation and utilization. This invention comprises a system of elements that combine to minimize the cost and complexity of a backup-capable solar power system. An element of this system is a prior-art balancer-based photovoltaic panel power optimizer whose power electronics are time-shared to allow an array of battery modules to power or provide supplemental or surge power to an inverter. Further elements of the system provide for rapid and low-cost installation, reliability, and easy and safe maintenance.

摘要： A self-powered wireless keyboard by modifying the structure of a traditional membrane keyboard having a volcanic crater structure. Not damaging the original membrane keyboard structure, a micro magnet core is installed inside a cylindrical protrusion block under the key cap as a mover of the induction power generation device, and an induction coil is wound in a key slot of the keyboard base as the stator of the induction power generation device. In this way, when each key is pressed, it will produce induction current. A layer of flexible solar cell can be laid on the upper surface of the key, which can generate electricity by collecting the light energy in the surrounding environment during the time of daily illumination.

摘要： Certain aspects of the present disclosure provide techniques for electric vehicle charging management. In one example, a method includes: building a graph representing an electrical topology of the electric vehicle charging facility and producing an updated graph by updating a state of the one or more network nodes based on electric current or power flow through the one or more passive electric components and updating a state of the one or more component nodes based on electric current or power produced or consumed by the one or more active electric components. The method further includes receiving a selected control strategy for the electric vehicle charging facility and adjusting an electric current or a power draw of an electric vehicle charging station in the electric vehicle charging facility based on the updated graph and the selected control strategy.
