Hi to all !
I am going to search for a picbasic sample code to implement a DC_DC converter having the MPPT ( Max Power Point Tracking ) feature. This power supply will be used for a small PV to prove the MPPT operation.
I plan to use a pic micro for this implementation.
Any help ?
Any sample code available as a reference?
Thank in advance.

PIC micro or a PICAXE?

Try the search function (enter MPPT) at the top of this page...you might find it's been covered quite a lot before :)

Depends a lot on how you intend going about this and what type of switcher you will be using and how you intend to control it's demand points.
Have a read of my finding here:-

Bottom line, don't try to use PICAXE PWMout to control the FET switching. The resolution simply isn't good enough.
Even using it to control setpoints, you need to bear in mind that it is only variable via a 10-bit control word.
