Abstract: A method is provided for setting an operating parameter for a DC to DC voltage converter. A load is operated, using a controller, with the operating parameter at a first value. A measurement of an actual inductor current at an inductor of the DC to DC voltage converter, a measurement of an actual load current are provided. The method then determines a reference value for the inductor current, based on the actual load current combined with an inductor current adjustment value based on a desired output voltage at the DC load. The reference value for the inductor current is then compared to the actual inductor current, and the operating parameter is maintained at the first value if the reference value is greater than the actual inductor current. The operating parameter is changed to a second value if the reference value is less than the actual inductor current.

Abstract: A method is provided for setting an operating parameter for a load on a photovoltaic power source, such as an AC signal or the speed of a motor, including operating a load, using a control system, with the operating parameter set at a first value, providing a measurement of DC source voltage at the power source to the control system, and providing a measurement of DC source current at the power source to the control system, determining the logarithm of the conductance from the measurement of DC source voltage and the measurement of DC source current, and comparing a reference parameter based on the logarithm of the conductance to a reference setpoint. Based on that comparison, the operating parameter may be modified for the load if the value of the reference parameter differs from the value of the reference setpoint by more than a threshold amount.
