  • Micro-solar insolation circuit
    Patent number: 6657419
    Abstract: A micro-solar insolation circuit having a boost regulator or DC—DC converter used to transfer the power available from a solar cell source, at a value close to its optimum, to a load is provided. The micro-solar insolation circuit comprises a comparator for generating an error signal based on a solar cell reference voltage wherein a modulator controller receives the error signal and changes its duty cycle based on the error signal. The modulator controller controls a high-speed switch in association with a synchronous rectifier for loss-less current limiting.
    Type: Grant
