Controlling converter for electrical energy generating cell with variable internal impedance involves adapting converter input impedance to cell internal impedance, sporadically performing calibration

摘要

The method involves adjusting the converter (2) input impedance (Re) with control electronics (6), placing a voltage-current characteristic specific to the cell (1) in the electronics for maximum power at different internal impedances, measuring the current to the converter and the cell voltage, comparing with the characteristic, adapting the input impedance to the internal impedance (Ri) accordingly and sporadically carrying out a calibration.
