  • SIMPLIFIED MAXIMUM POWER POINT CONTROL UTILIZING THE PV ARRAY VOLTAGE AT THE MAXIMUM POWER POINT
    Publication number: 20090189574
    Abstract: A converter system adapted to be connected between a photovoltaic power source and a load comprises a converter circuit, a control circuit, and a PWM generator circuit. The converter circuit is operatively connected to transfer energy from the photovoltaic power source to the load. The control circuit generates a raw control signal based on at least a voltage generated by the photovoltaic power source. The PWM generator circuit is operatively connected to the converter circuit and generates a PWM switch signal based on the raw control signal. The converter circuit transfers energy from the photovoltaic power source to the load based on the PWM switch signal.
