constant voltage of mppt

Hi friends,

i have simulated pv with mppt and dc to dc boost converter.

the problem is this: when I can not get a constant voltage in output of bost converter. If I want to connect the dc to dc converter to a grid, how it's possible to get constant voltag eof converter while mppt control changes this voltage?

you have to design feedback controller for your converter, you might use type 2 or 3 K-factor

[Hossein]

you can use another converter to regulate the output voltage...

Sir, I also have the same question. How to stabilize output voltage while input change ?
