Self-optimizing energy harvester using generator having a variable source voltage

摘要: A self-optimizing energy harvester comprises a thermoelectric generator coupling to thermal source, producing source voltage greater than minimum start-up voltage, where the drives boost circuit and feedforward circuit, delivering power load. conventional has maximum output only at input for which fixed set point resistor is chosen. The dynamically optimizes according dynamic resistance, thus increasing wide range of voltages, relative using reference resistor. resistance sum variable resistance. sample element forms differential between elements, corresponds voltage. chosen establish
