Certainly an excellent and complete SMPS!





Remembering that this project I'm just the "designer" ... More information on its operation, and other clarification questions directly with Leandro this topic:

FONTE CHAVEADA 1000W EP1000

Can post in any language, will surely be all very well welcomed!

Renato which the function of this relay and how it works.
the scheme to operate on 220 volts 110/220volts the key is turned on or off in the capacitor?
Click to expand...

The 10W/4R7 resistor prevents momentary short circuit the capacitors discharged cause when we turn on the power. Soon after full charge these capacitors the source starts and wrestles the relay that makes the direct connection, "jumping" the resistor 10W. This entire process occurs in a short period of time, almost imperceptible.

For connection at 220V = No jumper
For connection at 110V = With jumper

Thanks for taking my questions Renato ....
I did the circuit would be a soft start ..
I have other questions:
- Can I use another fet and what would it be? do not intend to use the power of 1kW at most 700w ..
- The 2200uf capacitors could use a larger value?

- What would be the calculation by turns to make another voltage if using fewer turns can use thicker wire to give more power?

Yes, yes you can use several Fets can be employed ...

You may notice that I left the accommodation of larger capaciores of 2200uF, just to accommodate larger values ​​as needed.

As for the transformer, I suggest you keep the primary, secondary only change if necessary to adjust the tension.

I wanted to make it clear once again, this project is not mine, I just did the layout (PCB) of the same. Who made the physical adjustments was his friend Leandro. We're friends, we do in partnership, in his spare time ...

Regards!!

Quasi complementary mosfet IRF640

I'm trying to develop a quasi complementary mosfet with:

Teste Mosfet quasi complementar IRF640 - YouTube

Fitness tests he did perfectly well in requisite quality, even better than some earlier ... But still need to adjust the best protection for the negative band, where the mosfets are polarized in the opposite direction and does not have much ability to absorb energy in this configuration , and thus lead them to an avalanche of tension and consequent short circuit when used at full power ...

I will use a few more tricks, if any of them give me a good result without affecting the sound quality, I continued the PCB and post soon ...

regards...

Tda 7294 + SMPS

Good afternoon friends!

I would leave all the important information:

Any project that I post in this forum, including this amplifier design is free. You can do what ever they want it, they can enjoy at home or even sell, make a profit, I do not care. Can change, they can do whatever they want it! The internet is a free (for now lol) environment. My designs and layouts not copyrighted, are open! Do not depend on electronics to survive, I have to machine only as a diversion, which I always found good friends and good reasons to continue!

A great week to all!

Soon I'll be posting a very cool layout, a stereo module for use with MP3 player Chinese:

An externally hosted image should be here but it was not working when we last tested it.


It is a compact PCB with embedded SMPS using 2 TDA7294 with independent stabilized for feeding the MP3 module and cooler outputs of ICs output ... missing yet make some adjustments, after all tested the files I post .

I'm still finishing the layout of the source of debunker (tests in the video posted above) ... Once finished I provide also ok!

Regards!

Ola Renato, Se possivel manda esse projeto em MP é o que Eu estou Precisando Grato!!!
