Design of Boost Converter

Homework Statement

Designing a Boost Converter

Relevant Equations

V = L di/dt

I want to do hands on designing a buck converter mainly understanding the selection of component values Inductor, Capacitor, Resistor, Mosfet, performing the calculations of Inductor current, Output voltages and Load currents. My first question is, i want to consider the below configuration of 10V, 4.8A -> 24V, 2A. Is the selection Ok? or i am failing in the first step itself, there is no particular reason for considering the above specifications, or please suggest better specifications which would help. Thank you in advance.

You mean boost converter there, right? That's what you've shown and you mention boosting the input voltage to make the higher output voltage.

Your specs assume 100% efficiency, which will not be possible. The best you can do will be about 95%.

Sorry yes it is Boost converter can I go with above specifications assuming 95% efficiency.

What are your L and C values and what is the switching frequency? What duty cycle would an ideal boost converter need to run at for your input-->output voltages? How does the lower real efficiency affect the duty cycle?

First, ignore the input current.
Design for a specified output current.
You know the input and output voltages.
Write equations that can be solved for D, the duty cycle.
Only then will the values of C and L be determined.
