Hi Everyone,
i am designing a MPPT solar tracking system with a 20w panel that generate max voltage 17.5v and max current 1.14A .Voc 21.9. Isc 1.22.And i am trying to design a buck converter to be able to get an output voltage to charge the battery of 12v and 2A . and i wanted to know how can i design it coz i cant get an accurate value for the Inductor and the Capacitor .and is it better to use buck converter only or do i have to use buck-boost converter? i am using an Arduino Uno for controlling the PWM , so can generate enough frequency from it to be able to use to for the switch? . if anyone can help please ?
