Default Calculation of resonant parts smps.

Hi all


Is there software to calculate this on picture? I am from myself a very bad calculator, I am shure not good with numbers, I can but need then help from software or calculator, I have one but seems I get strange results, maybe the explane on the project is not clear.

I have seen in past software who can do this kind of formulas, so maybe someone can tip me.

thanks

No, because I have never work with it and I think learn it is a big stage, maybe matlab?

I do use LTspice and sim, it works also to find resonance points.

I do not now if a fase shift controller chip can be usedm now it regulate by change frequency witn a vco, a fase shift do only shift one output but keeps
duty cycle de pendent of ramp pin.

Excel is much easier to learn than Mathlab...

Maybe but for me, a 29 years old guy it is difficult, I am not so good at software.

but maybe there is special software for calculations? sometimes the formulas are so unclear if these are henrys, microhenrys, ohms and hertz or kilohertz.

I do now there are scientificic calculators also on the internet.

But I am not such a mathboy like in stargate universum.

Hi

Yes I have found these but seems that for smps resonant calculations things are slighly different, like load independency so formula is different, )except serie resonant LC) but for resonance I did use this, internet is full with them but there are much more calculations for the smps supply, I also did find smps calculator who let calculate on base of output and input voltages and different topologies including resonant type, but still there is much to learn here, so I have now printed 100 pages of info and go into the woods with a pot of beer and read surrounded with nature and singing birds.

Resonance smps has some complicated resonance where also the leaaking inductance of the output transformer is included, however the fase shift topology do different, using a coil who do saturate above some current and so lengthed the soft switch of the igbt or mosfets to en broad level, the normal resonant do put out a sinusoidal signal who go to the output transformer lowering the EMI to a very low level, but also with fase shift this happens very well making a very clean smps supply..

One smps supply is for the hybrid, put out 250 v 200 mA 2 x 65 volts 20 amps, and 14 and 8 volts 5 amps.

Enough projects, maybe even a little to much.

thanks for the links.

I did see your circlophone amp, nice, I have tryed a bias servo in mine allfet circlotron who is a real circlotron but did get trouble, maybe bacause the missing ground potential, who excist only through a 150 ohm resistor, yours is much easier to implement, and it is a very nice looking amp.

Thanks for the links.


regards
