    Inductor design using a ferrite

    Thank you L Demon, From my learnings, the core will saturate from an excessive flux, and the saturation will generally not depends whether or not the PWM is higher than 50% (but it is of course all related because of the Ton). The reason is if Bmax>(L*Ioutmax)/(Ae*N) or Bmax=((V*Ton)/(Ae+N)) +...

    Inductor design using a ferrite

    alright so with a little bit of research and elbow grease, I'll have the pleasure to answer myself like a fool [rednose]. I figured that you need to take an inductance factor that is less than what you calculate otherwise you're going saturate the core, even though it would be less of a hassle...

    Inductor design using a ferrite

    Here is the datasheet, I do not know how to include 2 images per post so sorryhttps://files.engineering.com/getfile.aspx?folder=f5abad3a-c34a-4b0b-8c16-7eb824c07abe&file=Core_Datasheet.png

    Inductor design using a ferrite

    Hi, I'm trying to design a buck converter but ran into some trouble trying to design the inductor. I wanted to make my own using a ferrite core. The maximum current of the psu including the current ripple is 1.2A and the value of my inductor is 330uH for my specific design. I calculate the...

    Tachometers

    Hi, I'm not a very experienced engineer but from what I know and based on your image, just gonna throw my ideas, I can think of 2 simple things (I don't think anyone mentioned it but if otherwise sorry). 1) Wouldn't a Y-delta transformer clean out the triplens harmonic ? so you would get a...
