Thanks for the words of support!
I read the procedure for the first launch, the frequency setting and death time are a bit unclear to me, as well as how many A/mm2 is the coil load calculated?
If I wind the coils with thin enough parallel wires, or copper foil, and use IRFP460LC transistors, I can use 100khz frequency as well?
SG circuit adjusts operating frequency via trimmer resistor?
Example:
I need 1000VA for the consumer, I calculate for +-50V/10A= 100V and 10A secondary, current density 4A/mm2, the required cross-section of the conductor is 2.5mm2 and it would be copper lacquered wire with a diameter of 1.78mm. Of course, it is wound with a wire with a diameter of 0.1mm or 0.15mm with the required number of conductors twisted in parallel, due to the skin effect... If I use a wire with a diameter of 0.15mm, it is necessary to twist 141 wires for 2.5mm2 ...
If you were to use 0.1mm thick copper foil, you would need a width of 25mm, and that width easily fits on a coil of ETD49 with a safety margin of 3mm on each side of the tape...
When calculating the primary winding, a similar principle, or?
I'm writing this extensively, because through reading this whole topic I came across a lot of wrong writing and incomplete calculations.
I didn't notice that someone wrote how much the current load is per square mm of the coil?
Here I am, abbreviated version of writing
