Hi Mister_rf,
I have .PDF,which was sent by you.But i unable to understand that winding volume and surface area caculation part that is why i raised thread
if you understand caculation part please expalin me in detail
Thanks
Srini
Hi All
let me know how to find Surface area of double E core (E80) and Total winding Volume(Vw) and Core losses constants (K*B^a*f^b, in which k,a,b constants) from datasheet of ferrites provided by manfacturer
Thanks
Srinivas
Hi,
i have seen some flyback converters designed circuits in that Y-Cap is using across primary and secondary winding of isolation transformer.I observed that either priamry side or secondary side operating at high voltages.For example priamry voltage is 300V DC and Secondary is 48V DC.
Let me...

Dear dipnirvana
on your 17th april reply
Let me now how can you say the noise is on 150Khz to 500Khz at around 75dBuV is differential mode noise? why not it is commonmode noise?please kindly explain in brieaf.
let me know,How can we tell this is differenetial mode noise or this is...
circuit for costant 5v without using smps
Hi saumya
The main function of varistor is
to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when triggered, they will shunt the current created by the high voltage away from the...
switching losses mosfet
Hi umery2k75 sorry i do not u r name.
Thank you very much for your reply.I know whatever the formulas you sent to me.But i do not know how to caliculate ton and toff times theoretically .i would like to know these values before going to testing or practicall...
mosfet switching losses
Hi all
i am designing DC-AC full bridge inverter.i am using mosfets.i would like to know power losses of mosfets.I do not know how to caliculate switching losses of mosfet.If any one knows,please kindly send design or application note or your own notes.
I am using...
Hi All
I am using Two optocouplers to my inverter mains mode to invereter mode application.I used one opto coupler for zerocrossing detector and another for mains sensing voltage.i connected these optocouplers inputs in series.is it working at all conditions?i am sending schematic as file.
if...
400v step up converter
Hi FVM
I saw your previous answer about boost converter duty ratio limitation.You told that you observed boost up of 12V DC to 400V DC with a standard electric ignition system in a car.
Let me know,are you not using high frequency transformer for that?let me know...
Hi
i think that your circuit may not work.I saw your zip file .You connected to converters in parallel.if any change in output voltage that will effect both converters.are you tested this?if working please reply to my mail.
