Dear All,
I have question about designing pfc boost inductor,
I would like to build pfc boost inductor with auxiliary winding. for my SMPS 100khz.
Its the first time for me,
I am confused about choosing the right magnetic core.
There is toroidal, E core, ER corewhich one is the best?
and if...
Hi All,
I have question about designing SMPS,
i have design half of my power supply,
I want to build 500W power supply with output of 24, 5, and 12, with switching freq 100Khz..
i have done until the pfc pre regulator, by using a chip.
Now the output is 400V,
and i would like to ask some...
Hi all,,
I have question about determine fuse,
I would like to build power supply which the output is 12V@25A and 5V@1A
I will try to build linear power supply,
My transformer is 220V -> 24V (500VA).
Could you tell me what is the fuse value should be?
Thank you
regards
Hi,
I would like ask about designing power supply,
I want to make power supply that will operate devices that need 12 V and 20A.
I am thinking to use fixed voltage regulator LM 7812, but the problem is i saw in the specification of LM7812, the output current is only 1 A.
I have an idea to...
I mean in the fast way, of course in the right way as well.
Could you imagine if we have to test a lot of battery, and each battery takes almost 4/5 hours.
Thats why there should be the way how to knowing capacity, internal resistance and temperature. even using battery analyzer.
Dear All,,
I have question about testing a battery,
I would like to test capacity, internal resistance, and temperature in the fast way. I tried it with default pogram of cadex(auto), but it takes to much time. it takes almost 4 hours each battery.
Thats why i try to find out the fast and...
