Hi there,

I found some equations for a buck boost converter. They are as follows:

kt χ Io= ΔIL(1-D)/2

(IL)max = ΔIL/2(1+ 1/kt)

I try my best to figure out the parameters in the equation

D = duty cycle
ΔIL = the change of inductor current
Io = Average output current ------------ Is that correct

What actually Kt ?

Best Regards

 

Probably something to do with frequency or 1/frequency.
Where did you find it?

 

I found this equation on an exam paper. They had mentioned only the value for Kt.

I want to know actually what it does mean?

Best Regards
