I want to design a sepic converter for photovoltaic system
but i dont know how to calculate the input and uotput voltage for design sepic converter
can anybody say to me what base the dc/dc converter design calculation is on?

hi
my problem is not design of sepic converter . i know all detail of sepic converter...
my problem is that i dont know my input & out out voltage of converter what should to be?
my input is pv panel and output is connected to a ac/dc inverter
i dont know what base of the voltage i have to design the converter that works in mppt area

PV panels put out either high V, low A...
Or low V, high A.

Your MPPT is somewhere in the middle.

Is your panel spec 12V? Then design for maximum power draw at 12V.
