How can take switch value (type of MOSFET to design hardware), If I have Dual Sepic converter, take the input voltages from 10v to 30v and the output constant 13v, by using PID control?
Dual Sepic converter
Not necessarily an arduino. It may not be the best suited microcontroller for this application. Here is what you need for good efficiency, good regulation, and small components:use PID control in Arduino to control switch
