Hi.I have made a current buck converter given a input current it regulates the output current by control of the duty cycle of a switch.You will need this simulator:

https://falstad.com/circuit/

and the circuit is the uploaded file.

I have 2 questions:a)It seems that Iout/Iin = 1-D and not D.Why is that?
b)In the specification of a load , it says usually the power and resistance of the load.Now since I have the current Iout=sqrt(P*R) so the duty cycle will be Iout-Iin/Iout

 

For those of us who do not download simulators and are not able to open simulator files, could the TS post an actual circuit of the regulator? And if there is an equation that defines what "1-D" is all about, or at least what "D" is defined as. I am guessing it stands for duty cycle, but that is only an unqualified guess.

Yes it is the duty cycle.Sure I will take a screenshot.

Falstad is a online browser simulator,no need to download anything

 

OK, the short answer is that the greater the duty cycle the greater the time that the power is off, not on.
