**EDIT** Wow this thread refuses to die, for you reading this make sure you see links in my signature, as there are lasers usign the boost driver. Proof of concept, no?
Hiya all LPF folks!
Well, after a bit delayed shippement, my new coils arrived , and I have finished my first boost converter!
If you do not know what I'm talking about, see thread in my signature, PART1
In short....
My new coils arrived, I planned my new PCB (revised one, not entirelly the same as last one), soldered everything up.
Current set resistor was 2.0 Ohm, resulting in 100mA aproximately.
So, 3.5 V drop load... 97 mA! So far so good. PCB dead cold.
I tried both 6x and 7x 1n400x rectifiers, both combinations resulting in same 97 mA , measured 97 mV over 1ohm test load resistors.
So, I won't make the thread as long as last time, spare you the reading, I am just going to say that this one is not completely finished either, will make another PCB next weekend, for easier placing of components, as this one appears a bit 'crammed up', and I had to improvise the placement of current setting resistor, as I lacked a bit of space there.
Anyhow, pictures of the driver:
And here is the video of it in action, experimantal setup for now only:
Disregard the mess on my table and my comment to my friend at the end "Okay turn it off"
Looking forward to 'perfection' of the driver next weekend and assembling everything in Cree C6!
