nice job bro..i also done similar project dc-dc converter only use simple ic CD4047 for switching frequency 50khz ,IRF 3205 and hand winding torodial core transformer...
I used transformer from dead car amplifier. They typically have 4-6 windings on primary and 12-14 windings on secondary. I dont remember correct value of switching freq but it was something about 35-50kHz.
It was about 80w (from simply formula P=UI, 32v*2,5A=80w). This thing works, but its too simple to use in real applications. No thermal shutdown, overcurrent protection, voltage stabilisation...Now it lay somwhere on the shelf in my lab. Was a good experiment to gain experience- thats all I can say about it. :)
Circuit used here is very simple similar to those from datasheeets. The "heart" of this DC/DC is a TL594 IC which is driving mosfets trought transistors. If You are interested in circuit You can e-mail me and I will sent it to You. :)
Thanks Normellow! :) In fact yes-it will get hot with applied load on motor. But actually this DC/DC isnt intended for use with motors. It was just a test. :)
Maximum output power is about 150w. As You can see motor isnt spinning very fast...
It is based on Texas Instruments chip TL594 and some FQP50N06 mosfet. Toroid is standart one that is used in car audio amps. Frequency is set to approx. 80kHz.
how much is the maximum output power? looks like a push pull converter with a ka7500(S494) and mosfets. what torroid are you using and whats the frequency ?

Can u send a schematic of this circuit? Can it be adapted toolts output 48 to 55 v?

nice job dude. i want to know what inductance value you used? where did you get it from and what is the switching frequency?

and what was the load, how many W?

Well done Guntixx
I have been trying to get DC to DC working but with less success, each time the IC blows up. I am nearly at a point to give it up...
you've done a great job, i would like to have the schematic Imight be successful this time?
bravo guntixx

Great job!
Do you have a schematic for the circuit you can share? Info on the windings and type of toroids used would be great, too.
Again, nice job!

It will get hot once you put resistance on the motor axel . A free running motor doesn't use any power. Nice motor !!!
