Hello everyone,

I am having some trouble in the following design problem. Wish I could get some insight on your behalf. Im doing this as part of my degree project.

I have to design the parameters of a dc-dc boost converter whose output is connected to a typical battery model ( a d.c voltage source and a series resistance representing the internal resistance). I am having trouble to calculate the Inductance L in series with the switch(maintaining continuous inductor current operation).

my input d.c voltage is from a range of values (16-32V) and I have to provide charging of the load battery which is a 60V-battery.

Any idea on how I can proceed?? I will be using these to build my circuit in Simulink.

Hi,

You need a boost converter to boost the voltage from (16-32V) to 60V, or you can use bidirectional converter, you can use either of the following models:
