Transformer design ang Formulas
« on: October 31, 2019, 11:53:20 AM »
See here and comments na lang from other/s and master/s

https://en.wikibooks.org/wiki/Electronics/Transformer_Design


Simpler formulae

A shorter formula for the core area (a) and the turns per volt (T) can be derived from the long voltage formula by multiplying, rearranging, and dividing out. This is used if one wants to design a transformer using a sine wave, at a fixed flux density, and frequency. Below is the short formulas for core areas in square inches having a flux density of 12 kilogauss at 60 Hz (see note 2):

    a = 0.1725 sqrt( P )


    T = 4.85 / a

and for 12 kilogauss at 50 Hz:

    a = 0.206 sqrt (P )


    T = 5.82 / a

a - area of core

anong proseso para makumpirma yung amperes ng secondary ng transformer build.
looking for confirmation at hindi computation. paki post kung paano gawin. t.y. sa magreply

ginaya ko lang nabasa ko sa kabila.
Peace!

Pinagsama ko yung transformer calculator ni Silvio Klaic at isang program ni Rod Elliot. Napakabilis. EI core lang naman.
Makikita na yung size ng wire at input/output voltage at power sa program ni Klaic, pero gusto ko yung calculator sa # of turns sa program ni Rod Elliot. Size of core lang ang basehan sa dalawang calculator na ito.
Generations come and generations go, but the world stays just the same. What has happened before will happen again.

Hinahanap ko iyong core VA rating ayun sa tongue area derivation. Iba iba kasi ang unit na ginagamit nila. At kababalik ko lang uli sa papel kaya windang na uli. Kung dati ng windang ngayon mas malala na.  ;D   Ngayon trying to derive the formula to get sa mga ginagamit na formula dito.

yung formula sa photo matatagpuan din to sa RDH4 kalimitan inches ito, sa metric hindi ko kabisado,. another site na pwede puntahan yung kay ludens at turneraudio,. yung flux density need din ng discussion.
In this world, whenever there is light, there are also shadows. As long as the concept of winners exists, there must also be losers. The selfish desire of wanting to maintain peace causes wars and hatred is born to protect love.

Ang alam kung base unit niyan ay weber/square meter conversion lang nangyayari at material grade ang laruan ng mga pogi.  ;D

E=4.44 (F)(N)(PHI)       base formula para sa sinosoid waveform.

Pmax =BmaxA   where A is the area of core.  in square unit.

kaya subtituting (P)phi para maexpand at lumabas ang betamax at ang bitamina "A" kaya nagiging

E=4.44 (F)(N)(Bmax)A  volts where betamax ay 1 weber per square meter. That is almost 65000 lines of force per square inch naman sa ibang unit. Kaya nagkakameron ng 10-8. O 1 gauss or base where betamax ay 1 tesla that is also equal to 1 weber per square m.  Karaniwan naman ginagamit na value ay malapit sa isang tesla.  Pinakamataas na nakuha sa ibang material ay 4. Pero hindi pa para sa transformer ngayon.
