LF357

Hello friends. Had at Linear Technology substitute for LF357

[raff33]

Over voltage maybe? Or wrong polarity?

yes ivconic wrong polarity
regards

[ivconic]

i have an accident with my delta pluse 10000uf Pops
and i have another one but i want to know what is the problem first i used power supply not battery and connect 10 k ohm between gate and source of mosfet what the problem to Pops
i am sorry for more question
i have 0.4 and 0.8 and 0.3 thickness of wire and i want how to make coil with good inductance and resistance what no of turn and diameter
????????????????????

can you write what the board sizes would be optimal in your opinion? what box you are planning to use? what mounting dimensions would be good in your opinion?

I don't know sincerly , if you mean that the work is in progress ok we wait some days

please KT315 , when you will post the new pcb of delta pulse ?

new PCB?

PEOPLE, CAN YOU WAIT A LITTLE? I do all as far as in me lies you all will get NORMAL WORKING AND TESTED PCB.

please KT315 , when you will post the new pcb of delta pulse ?

I found a link to Geoteh forum. http://www.geotech1.com/forums/showthread.php?t=17909, program and budget for the coil does not work

What is the problem?

According your post #21, you wound a loop of 250mm diameter using 25 turns of wire with a thickness of 04mm, resulting in an inductance of 500uH.

Using the calculator, as follows:
Inner radius = 125mm
Wire thickness = 0.4mm
Number of turns = 25
The calculated inductance is 497uH

Looks close enough to me!

Hi Vujo
It seems clear that you do not like to use the Coil Calculator!!!!!!!!!!!!, the -number of turns 25 wrong,the correct of number of turns 32tu.
-wire diameter of 0.4mm wrong,the correct wire diameter of 0.5mm.
-try R5 = 1K~2.2K.
Clear from your words that mistake in the coil, appears to be sound like the pcb good.

Hi VUJO

-try to use Coil Calculator to make good coil.
-try R5 = 1K~2.2K.

It may not be the best prepared and coil,but can not be a reason not to.I think there is another implication.Montage works well,but I do not know.Do you have the correct components

Is this the demo version that times out after a number of uses?
