Why don't yu try a Linear Adjustable Regulator just after this SMPS ?? You may design your SMPS ( for instance 85-270VAC )then you can connect a variable regulator then.. SMPSs work still rectified line voltage so DC.flyback is a good choice..
35kV high voltage can be generated with much lower mass flyback transformer but there is a relationship to the maximum energy that can be stored and transferred by flyback method in gm/watt which is related to the Bmax saturation level of the core and losses in Watts/kg of the core. What are you trying to prove again? (...)
With the second scheme, you changed the flyback into a forward converter, not what you want, I guess. Twe too high output voltage in first case isn't a problem of transformer design, it means that the feedback circuit isn't working. Your schematic has a missing ground connection, but there may be other problems too. The (...)
Just a suggestion: Since output power is low, input peak current shouldn't be too high. So, you can try with a single switch flyback, using a 900V MOSFET, ensuring that the snubber you design keeps the peak drain voltage of the MOSFET to a sufficiently low level.
who knows the how much drop voltage flyback converter or curve current vs voltage when loaded......
hi u can make it very easily use a flyback transformer anda simple oscilator with two transistor or with a 555 IC then make a ac voltage with your battery with a frequency about 20khz(try the to find best frequency) then on the other side of transformer change your 600v ac voltage to dc with 1n4007 diodes.
The task is not as difficult as it seems. I have some experience with building flyback converters up to 150W so I would use flyback smps to power that LED matrix.
Forward or flyback convertors are your solution, but I think for your application Forward converter is better selection, thids due to high level of output current. also I think it is better to use integrated switchers available from International Reactifier : due to lower voltage and higher efficiency. another (...)
Hello Jav2xar, Sorry, but I didn't get any schematic. It seems that this monitor, or at least some batches of it, have a design problem in the high voltage/flyback Tr.... I have two of this an both failed in the same way. The representative here has repaired a lot of this, also failed in the same way. Best regards P.S. (...)
to generate high voltage i thiunk the normal flyback topology is not sufficeint as u will ned a huge number of winding in secondary but as in TV horizentalor as in Spark ignition there's a good ways to generate those hiugh voltages this way depends on resonance , wher the charged primary inductor in (...)
