Hi guys
I wondering if you finaly succeded with this project.
And i would like to ask your help.
I'm an electronics and computers student in sweden and this is my third year.
I'm doing a project course where i have to dimention and build a DC/DC convertor with the following caracteristics:
Vin 12V
Vout 36V
Iout 6A
Pout 200W
We are gonna try to drive a LED array from a 12V DC battery.
I did notice that my project it's very similar comparing to the project you guys were working with. That's why i would like to ask you guys, specially takao21203 couse you seem to have more experience on these king of constructions.
Can I basicly use the same circuit that you have build on LTspice with the same components?? or do I have to modify a lot and I'm misstaken all the basic theory???
I will attach the circuit that i did build on LTspice doing some basic calcules over a basic DC/DC boost convertor circuit, this way maybe you will get a better idea about what i'm looking for.
My teachers comments after viewing my first LTspice circuit were following:
C2 I_ripple = 8ARMS (16A pulser), (205uF is not standard value, 220uF closest)
I_L1 18A aprox, (how is it a 45uH 20A bobine look like? , (sounds expensive)
M1 has 50W power loos, reducing gateresistans to 1 ohm you could reduce power loos to 45W (10%), hard to cool these power looses.
Finally the circuit has aprox 75% efficiency, litle low.
Well guys thank you for your time and for your help.
I hope you read this message and are still using this web site
Hope here from you soon.
Greetings!!!
