dc dc convertor 20a 12 24
Hi all,
I would like to design DC-DC converter with following specifications.
Input : 12V from the car battery
Output:24V/20A
Topology: Boost converter
Voltage ripple:0.1%
Current ripple:4A (Iin become 40A as per calculation )
Operating frequency:100KHz
Delta Il taken as 10% of Iin
As per the calculation i got an inductor value of 66UH and capcitance value 4200UF. Can anybody verify my design. I need to know how to select ripple current with unknown input current and operating frequency. If anybody comes forward with design idea please send a mail to gs.srikanth(at)rediffmail.com
Advance Thanks,
sri
