    Transformer N value ?

    Everyone,

    I see N value from the transformer design,
    Is that the real value I must do a winding ? N = 23 so 23 turn on the core ?

    Cheers

    So the number of windings is related to voltage and current in proportion to the input. As the secondary windings increase compare to the primary windings voltage will increase in the secondary.As the voltage goes up in the secondary the current will go down. Voltage and current in the primary are inversely proportional in the secondary. So if the voltage is increased by double in the secondary the current will be 1/2 in the secondary. I forget the turns ratio. I believe double the turns in the secondary it doubles the voltage. I am not sure of the later, but you should be able to find that formula online.

        correct me if I'm wrong
        Vp/Vs = Np/Ns
        Vp/12 = 45/7
        So Vp will be on 70.14V

          and for N0, is it the closest to core ? from that layout ?

            I would say the primary voltage is determine to how much you apply. So the equation is correct if you do not know how many volts you apply and you know the turns ratio of the primary and the secondary and the voltage of the secondary then you can figure out the primary voltage.

                Samsung 2233SN no CFL backlight
                by Spoonicks
                Hello,

                Have a Samsung 2233SN with no CFL backlight. Testing with a flashlight, I can see the image is displayed, but the backlight fails after some seconds.
                Sometimes, after being off for a while, the backlight will remain on for a couple minutes, but most of the times it fails immediately.




                I tried to follow the guide present in this forum, but so far I haven't de-soldered any components. I need some advice on how to proceed to diagnose this display.

                Following the guide I tested the following:

                Technics Transformer question.
                by angelos
                Hi there,
                I have this CD player from a Technics Component unit whose mains transformer is blown. The primary winding is open circuit. This transformer has many secondary windings on its secondary side. This transformer is obviously obsolete.
                I need to know if my trick for a alternative transformer will work. Please check the attachment for explanation.
                I want to use three separate transformers to be equivalent like the original transformer.
                The only thing a bit dodgy is the connection of the 9.6V and 12V outputs of which there is a interconnection between the two windings....

                KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
                by momaka
                For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
                http://www.rmac.kingwin.com/products.../abt_650MM.asp

                I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




                What mostly drew me into buying it is its 2x PCI-E power connectors...

                KDM 480W PSU upgrade succes! (opinions?)
                by bauto601
                Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
                A "nice" YoungYear unit? - Badcaps

                The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....

                Is it possible for transformer substitution?
                by mikey5791
                Hi all,
                Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
                Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
                My questions are
                1. How do i test to see if the transformer is in good working condition?
                2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
                Hope you guys understand what i was asking. My intention is...
