Power supply and method for controlling it

摘要: A self-powered apparatus includes a solar power cell, battery, and load. The load may include one or more functions performed using provided by both of the cell battery. inclusion battery permits to be sized much smaller than if was only supply power. programmable controller selectively regulates also whether supplies Switching circuitry, controlled controller, couples energy for powering In preferred example embodiment, and/or charge super capacitor, which then is determines prioritizes function requirements, based thereon, will powered priority requirements amount that can supplied as supplemented
