Title: Circuit for regulating power source to maximum power point
Inventor: DELEPAUT CHRISTOPHE
IPC: G05F1/67
Filed: 2003-08-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power regulation circuit in which a graph of supplied power according to voltage of a power supply terminal has the maximum value.  <P>SOLUTION: In a power source 10 such as a solar generator, the graph of the power to be supplied according to the voltage of the terminal has the maximum value. The power source is provided with a DC/DC converter. For regulating the power source, a target value of input power which increases as long as a differential coefficient of input voltage of a converter to time is larger than a first negative threshold and decreases as long as the differential coefficient of the input voltage of the converter to time is smaller than a second positive threshold is applied to the converter. A rate of change of average power when the target value increases is selected so that it becomes smaller than a rate of change of a reverse sign of the average power when the target value decreases. By such adjustment, the power is supplied at the maximum power point and the adjustment is easily executed.  <P>COPYRIGHT: (C)2004,JPO
