You need to post way more data, such voltages,secondary ones, frequency, etc. but most important, the circuit you will use.
hello sir thank you for replyingyour core area is 9cm x 10cm or 90cm, therefore turns per volt is 42/90 or 0r 0.47 turns per volt, you got a heavy toroid there...caoacity estimated at 125va per kilogram of core weight....
Sir how can i decrease lossed power..??
in this way i get only 4000w how can i increase this to 4500w and above.?
my core can handle till 8100w.!
220v for primary.,,27v for secondary,You need to post way more data, such voltages,secondary ones, frequency, etc. but most important, the circuit you will use.
My Hz is 50..
What do you mean’’ THE CIRCUIT YOU USE..?’’
Capacity is application dependent - that’s what JM referred to. As an inverter you can get more out of it than as an audio amp supply. You can cheat the turns per volt a bit if you‘re willing to live with more core losses and mechanical buzzing noise coming off of it. If you are not going to grid tie, you can up the frequency to 60 or even 100 (and legitimately increase the volts per turn - to a first order it’s linear with frequency). Intermittent loading may be many times the continuous, so 500 extra watts is no big deal if the driver circuit is up to the task.
If you have trouble with these calculations, a 5 kw inverter could be dangerous or at least very tricky to build. The driver circuitry is much harder to build safely than the transformer. Are you doing a PWM sine wave or just a brute force square wave with modified duty cycle like the old Tripp-Lite’s? The latter is relatively easy but not foolproof, and not suitable for all types of loads.

The toroid does not work "alone", you WILL use some circuit to drive it.
So post it here.
Also, not too sure about your needs or application:
And you need 27VAC or DC?
What is the intended load?
As you see, the whole Forum wants to help, but we need more data.

does not sound like an inverter at all, you sure you don´t mean a "power supply"?220v for primary.,,27v for secondary,

i have only problem with making the toroid transformer..!
i just wanted to get more power and in this situation if i get 4kw it’s ok too..!
Can you look at this pleas ..?The toroid does not work "alone", you WILL use some circuit to drive it.

I want to make like this transformer..!
Ok.
You have all the equations at 0:48 in your video.
Write them on a piece of paper, fill in values you have and do the Math.
The whole inverter transformer construction is shown there, just follow it.
