Latest Patents
One of his latest patents is a control circuit for a solar-powered rechargeable power source and load. This innovative circuit is designed to control the recharging of a rechargeable power source using a photovoltaic panel. It powers loads such as lamps for walk lights. The circuit is engineered to charge a rechargeable battery whenever sunlight is sufficient to create a potential across the battery that exceeds its current potential. It can also sense a decrease in voltage across the photovoltaic panel as ambient light diminishes, allowing it to energize the load accordingly. Furthermore, the circuit prevents the load from being energized when ambient light is adequate for recharging the battery. It provides positive feedback at the load's turn-on, hastening activation and offering hysteresis. The design allows for adjustments to the hysteresis bands and shifts the turn-on and turn-off thresholds. It ensures adequate current for guaranteed turn-on, even with low leakage solar panels. Additionally, the circuit can exhibit hysteresis at load turn-off, preventing cycling on and off, and can raise the load turn-off threshold above the level where the battery is significantly discharged, thus accelerating battery recharging. A further embodiment includes temperature compensation for enhanced performance.
