is there any design for voltage & frequency step up in the transformer?

What didn't you get from your previous thread?

added up with the above question i want to know what will happen in secondary side frequency while transformer action? Is it increase or decrease ? both in practical & ideal cases?

As you've already been told, a transformer will not change the frequency.

It was still funny as hell, even if off-topic.

No, Not like that. If a frequency converter can added with the secondary side it can change the frequency. My question is "Is this design can be possible in practically?"

You are talking apples, oranges and bananas. The transformer is an apple and a frequency converter is an orange and the frequency is a banana.

With just an apple, the output banana is the same as the input banana.

If you add an orange after the apple (notice the "after" and not "to"), the output banana will no longer mirror the input banana.

That, my friend, is worthy of being put on a t-shirt!

I suppose one could always chrome-plate the orange.

If you want to discuss devices with different input and output frequency, you must learn to stop calling them "transformers".

A transformer consists of two coils of wire on a common core. The change in the current in the primary coil generates a changing magnetic field in the core which generates a voltage in the secondary. Either coil can be the primary or secondary. The voltage for each coil is proportional to the number of turns, so if the secondary has more turns, the voltage is stepped up. If it has fewer turns, the voltage is stepped down. The frequency remains the same.

If you want to change the frequency as well, there are two ways to do this. The first is to run a motor which turns a generator. Nowadays, motor generator sets have generally been replaced with electronics. The input power is rectified (converted to DC) and the DC drives an inverter circuit which converts DC to AC of the desired voltage and frequency.

Oh, I thought they are called Optimus Prime and Megatron & so forth? Confused?

Sure there are. Are you looking to build a converter yourself? If you are, rest assured that that will be a major undertaking. Given the nature of your questions on this thread and on the other, you first need to master basic electronics and learn what a transformer is and what it does - and does not do.

Transformers and converters are vastly different beasts. Converters are complex, especially if you need a fairly pure sine-wave output, and especially at high power. These problems have been solved by others and you can buy their solutions in the form of off-the-shelf converters.

You can do it, but you won't be calling it a transformer. Then, you realised that in your earlier thread, didn't you?

Yes and No.. its called a Medium Voltage Drive.... or MV-(VF)D, but its not a transformer.
