kam
im really trying all my best ... and believe me want to learn!!!
did yu see the image i attached on ma previous reply?
a circuit diagram that shows one of my projects.
Rcell is actually a battery cell. Its equivalent resistance is the internal resistance in the milliohm range (0.1ohms)
When charging up this cell, the voltage across it will increase from abwt 1.1V to abwt 1.6/1.7V ... another problem lies when iv set a particular Vout = 1.2V initially
The comes a point where Vout = Vcell and there wont be any current flowing through the cell. Thereby not fully" charging the cell. i need a mechanism that will measure Vcell and increase Vout accordingly until the cell is fully charged .
Theres a method called Negative Delta V when charging secondary cells. and that is when the cell is fully charged. it will tend to discharge and this will invoke a negative or rather a drop in voltage. by this detection the converter will disconnect from the cell.
so in essence its not only the feedback problem i have . its also this change in Vout i need to implement
kam yu seem to have a huge idead with this . yur assistance will be appreciated.
coding will not be a problem for me ,,, guidance in the right path is wat i need.
thank yu
