Need a power supply circuit 18 v 25-30a

Topics / Questions
Added 35 comments
Of the Lord the inhabitants of our site. I really need a power supply circuit of 18 v 25-30a. For manual battery circular 18 v. 600 w. There is a Soviet school step-down transformer with outputs of 12, 24, 36 and 40 v. A circuit for the indicated output is required. I searched for it myself but didn’t find the needed volt, it’s not enough (a lot). then amperage is not the same. I tried the impulse block - it does not pull. Batteries new to buy, easier to throw out. All hope is only for you.

Seem not faded, but went to visit Delausyusam.))) Nikolai drove him a ticket.))))

If this is a "school" LATR, then this is an AUTOTransformer, it is even unsafe, there is no decoupling of the secondary winding from the 220 V network. First you need to wind the secondary winding to 30 A, 18 V.

Do you want to adapt an existing transformer? Then it should provide a load current of up to 30 Amperes, this is a bit much for the "school Soviet". Send the dimensions or power of your transformer, or the current of its secondary windings, or at least the thickness of the winding wire. The output voltage of the transformer provides up to certain ultimate loads. To power your 600 W machine, you need a 600-1000 W transformer or transformerless (pulse, converter) power circuit.

The T1 power transformer is used from a color TV set of the Rubin type TC-320 with copper windings, it is also possible to use it with aluminum windings of the TSA-270 type. Changing the required voltage is carried out by winding the secondary windings.

And to the question about the parameters of the school transformer, instead of the answer, it followed:
transformer from the school cabinet-kilowatt

Do not understand what they want from you - ask! And not ham!
For the most intelligent, I’m chewing: what is the permissible operating current of each winding, the common winding with taps, or individual windings for the indicated voltages?

Something tells me that the answer to the question is not very interesting for you, because it’s a specific question

They are trying to help you, to extract something meaningful from an illiterate stream of consciousness, and you don’t even want to answer specific questions. fool

I already made a circuit from a bridge and a conder
Which winding was connected to?

Why wind something what i don't have
Do you think that just a circuit diagram drawn on paper will twist your circular? nea

The amateur radio circuits given are for another, for powering the radio units. To power the electric motor with direct current, a simple circuit below. And the collector needs to be cleaned

The battery does not spark. Sparks from the floor of the periudus

And above:
e i did the circuit from the bridge and Conder sparks the collector. Need stabilization.

Does anyone understand what he wants, generally ????
Then he has a diode bridge with one (!) Half-cycle. Then let’s squeeze the PSU so that there is no transformer in it, but a “school kilowatt” ...
Then he needs stabilization already (Moreover, not a word about why and to what extent his voltage jumps!)))
And, if the voltage jumps, then what does the "half-cycle" have to do with it ??? And why does he think that it sparks from power surges ???
Answer-read carefully the text.

If you write, think carefully what you write.)))) Either clearly explain what you want, but don’t know how - "silence is gold" ...
And further...
Do not consider yourself smarter than everyone ....

.... especially if you’re not even kicking a foot of what you are asking questions about ....

P.S. Sorry, dear users ...But, usually, a person gets the fastest just when they speak his own language.))))

You didn’t have Ukrainians in your family, the same stubborn one, “he cares, but he is a white dog” and “don’t teach me how to live, better help me financially”. Take out and put the stabilizer circuit of that, I don’t know what, but so that it works for me. You ask for advice, not really understanding the problem, but take the circuit from the welding inverter and stabilize the voltage instead of current, although you only have to think about asking to be done for you.

Why wind something that I don’t have. Or maybe buy a microwave? in order to remove the trance from it ???

sparks collector. Need stabilization
Sparking is not associated with stabilization.

On the manifold, strong sparking is obtained
Strong sparking indicates an armature malfunction, a break in one of the windings or a short circuit, the shape of the supply voltage (respectively, the current) does not play a special piano, the speed control of the collector motors is mainly pulse-width, household tools generally do not spark at the break. Another thing is that at constant current the power is higher with the same dimensions. And yes, the school LATR and a wire of at least 4 squares on it.

I would have a diagram, not questions. Circular parameters I wrote 18 v. 600 w. At maximum loads, it takes up to 30 amperes. Measured by professional-ticks. on this transformer that I already made a circuit from a bridge and a conder sparks a collector. Need stabilization. I didn’t find the parameters I needed on the Internet ....

And what are the parameters of this block?
I powered a screwdriver from a computer power supply unit (12V, 28A), it couldn’t do without dancing with a tambourine, at the moment the power supply screwdriver was turned on, it went to the defense, but if it turned on at low speeds, it worked at full speed and under load, and at full speed, until you let go key, had to conjure with the scheme.

Try rewinding the transformer from the microwave. I think stabilization for the circular is optional, a good enough diode bridge and capacitor.
