Homework Statement
I have some very big difficulties with this assignment, hope someone can give me some clue in the right direction
Design the boost converter represented in and operating in continuous conduction mode (CCM). The usual
hypotheses apply: the output voltage is considered to be constant and equal to Vo, the input voltage is
considered to be constant and equal to Vi, all the components are ideal. Remember to choose a correct value
of inductance in order to guarantee the operation in CCM in the whole range of output current.
Data
Input voltage: Vi = 10 V
Output voltage: Vo = [15; 25] V
Output current range: Io = [2; 5] A
Switching frequency: fs = 50 kHz
Maximum output voltage ripple admitted: Δvo,max = 0.5 V
Questions
1. Switching period: Ts
2. Output power range: Po
3. Inductance: L
4. Duty cycle range: D
Homework Equations
The main problem is that I have no idea on how to find the inductance! I know the solution for a Buck, but not for a boost. I have attached a drawing of the circuit.
Will really appreciate any kind of help or hints!
Best regards!
