I am using keil uv.5
recently i got few Nuvoton chips - M031 and M032
I installed all the needed package .. so i can start a new project and select the mcu etc.....ok
I got a zip folder downloaded from the nuvoton site having example code etc.
but when I unzipped the downloaded folder mentioned...
The core above is unsed EPCOS EE42/21/20 N87 cores, bought in 10/2019.
I went to buy small EE cores , but also bought some ee42,36 etd 39 etc.
I didnt have any bag with me so I took a packing box they gave me , shown below.
I didnt not move the cores out of the box, took few for some...
I will try to get this ..
The ferrite torroids i mentioned above was bought couple of years back when I was buying E cores for a flyback. I wanted to use it in a buck (I didnt know much about Iron powder cores etc.. then). I just wanted to know if can use it for something , i dont want to...
I will go with trial and error method. starting from base and go up to find the limit.
the torroids i mentioned above, especially:
R25.3x14.8x10 - T35
R31.5x19x12.5 - N41
I bought this from a shop (this was only available). I have 10 nos with me.
how do we gap this torroids.
if we stack...
My requirement is related to solar. - IN - 45v or 90v (series or parallel - at present 45v - 2 in parallel).. output 12-14
say 15-20 amps only. But thought about going with a 30amp design
I went through micro metals site and saw options. They all use a minimum OD=26mm cores and next one...
To keep things simple ,, how many circular mills needed for 30amp. if i use 25awg wire how many to use in parallel (I have limited options) .
If use a single torroid , what size is recommended from your experience.
It is somewhat confusing for me, that is why i asked the question.
kindly correct me if i am wrong
above said eqn: awg 19 wire, 4 in parallel , 5 layers.
so i use 19 guage wire around this core wind 10 turns (or 12 - to get needed length per wire)
then i cut 4x5 = 20nos 19awg wire as measured...
when we design a flyback , we calculate inductance etc... then calculate the airgap.
For instance lets say the calculated inductance is 380 micro henry and airgap is .25mm and ''X'' no of turns.
But I have a core with .5mm airgap (from source).
So then just by finding the AL value of the...
so enery can go either direction in all types of mosfet??.. same with BJT also?
unlike in the above design, if i ignore the lowside mosfet and replace it with a diode and also use an high side only driver like IR2117 , is it possible to drive multiple mosfet ? And also with the bootstrap...
so the low side diode is doing the job of freewheel diode. I had a misunderstanding that an n-channel mosfet conducts from drain-> source (and not other way around). and then how the body diode acts?
Most of the above questions I asked is for " (minimum)things I should know " , not to try risky things.
I am in asia, the unit came with an european pin I think ( with the earthing pin hollow). i swapped its power cord with my HP 1020 laserjet cord which has three pins..
so the earthing of...
