Abstract:
A system for providing power from a source providing source power at a source current at a source voltage to a load receiving load power at a load current at a load voltage, the load having variable amounts of load demand for the load power, the source providing variable amounts of the source power, the system comprising,a converter coupled between the source and the load, the converter for converting the source power into the load power, anda maximum power tracker connected to the converter and the source for controlling the source power and the load power, the maximum power tracker sensing the load current and source voltage and controlling the converter for maximizing the source power to a peak power point at a respective peak power source voltage when the load demand exceeds the source power, the maximum power tracker increasing the source voltage for increasing the source power toward the peak power point when the source power is below the peak power point and the source voltage is below the peak power source voltage and when the load demand exceeds the source power, the maximum power tracker decreasing the source voltage for increasing the source power toward the peak power point when the source power is below the peak power point and when and the source voltage is above the peak power source voltage and when the load demand exceeds the source power, the maximum power tracker maintaining the source voltage constant at the peak power source voltage when the source power is at peak power point and when the load demand exceeds the source power, the maximum power tracker generating a control signal for controlling the converter to control the source voltage for operating the source at the peak power point when the load demand exceeds the source power, the maximum power tracker controlling the converter for peak power tracking when increasing or decreasing or maintaining the source voltage when the load demand exceeds the source power, the maximum power tracker regulating the load voltage at a regulated load voltage when the available powers from the source exceeds the load demand.
