I've been driving it in push-pull and I've got max 5 watts before the voltage collapses at 50 and 60khz. any help on why is that and how can i get more power? Np= 4+4, Ns= 8+8.

higher or lower frequency it has worse performance

Es selamun aleyküm Is this calculation method valid for all ferrite cores?🇹🇷

[@HaseebElectronics]

yes dear,we can use it

[@AmjadKhagga]

Transformer formula: TPV=10^8/4.44*Bmax*f*Ac Descriptions: TPV= Turn Per Volt 10^8 and 4.44 are constants Bmax= maximum number of magnetic lines of force easily passable through one square inch area (which is 65000 lines per square inch for small transformers i.e. below 36 watts and 60000 lines per square inch for larger transformers i.e. above 36 watts, this is also called flux density f= frequency in Hz Ac= Area of core in square inches why in square inches? because we are counting flux density through square inches, we can convert it into square centimeters (or any other unit) if we wish. ------------------- An other formula to find Area of core, provided you already have wattage in your mind: Square Root of watt divided by 5.58 i.e. √watt/5.58 in other words (watt)^0.5/5.58 Note that 5.5 is a constant.

[@HaseebElectronics]

perfect sir. 4.44 is constant for ac signal, but for square wave pulsed DC it is 4. Bmax will change according to core material type and frequency, for example for a P material ferrite core switching at 20KHz will allow 1600 guases and at 100 KHz it will allow 900 guases

[@medjoui7600]

For one E it is 1. For 2 E's it would be 2, but due to area losses in winding en used space by the plastic bobin holder, 1.5 is used (1.4 if badly winding)

[@mdislammdislam6183]

Sir it’s formula EE or EI which one?

[@HaseebElectronics]

for EE & EI we must have to select the core area properly. becayse it is directly involved with core power handling if we will slect the EI core, the bobbin length and window area will area differ than the EE core okay i will explain it soon

Iron core is only usable for frequency's far below 1000 Hz. You need to know the Bmax/f curve.

Based on the chart 50Khz would be closer to 1600 gauss. Calculation comes to 1416watt and the difference of 1100watt could be attributed to the bobbin.

this is so strange that in formula of Po are being used Gauses, cm, and current dencity in mils..... In SI system B is measured in (T), distances in (m), and current density in A/sq.m...

[@inarinukka7729]

In the real world things are bit different. It is a fact that there are many different types of power ferrites. And also the permitted flux densities etc. and therefore transmitted power are also different. For example, a much more realistic calculation (which I use in real life) gives completely different numbers for the same E55/28/21 core. For example, it is more realistic that in the case of Ferroxcube 3C85 and 3C96 ferrites, where same E55 core size gives a difference of about 1000W, and this already at a frequency as only as 50kHz, as the indicator of different ferrite brands of other manufacturers is also different. By the way, the same Ferroxcube E55 3C96 core is suitable for about 3.5kW conversion at 50kHz and !without forced cooling!, and here * these calculations have not been taken to the last limit *, but there is still some margin left. It is not a problem to take 3-4kW of power from E55 core at frequencies below 100kHz, and at 100kHz the 3C96 with the same 3C96 is good for about 5kW conversion. PQ cores are much better, the PQ4040 size can easily use 3+kW of power as a transformer for example in a half-bridge topology. These facts are easy to check and proven - even by looking at commercially produced inverter welding machines. 1100W from E55 core? It's a bit waste of good, big cores if an E42 or ETD39 core does the same job. By the way, there are still losses when using thick single wire for windings, etc., just like in commercial PC power supply units - I did an experiment and new power supply unit with a power of barely 300W with its ETD34 transformer, which was produced with windings with thick solid wires, gave almost 470W after rewinding with litz wire and only because of this modification - so the use of litz wire is very important if the powers/Fq`s are higher, even 40+kHz gives better results in terms of litz efficiency (at least in my favorite, half-bridge circuits)
