## Advice on my first SMPS device.

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..

## Highvoltage design challenge.

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? (...)

## The way to wound flyback transformer

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 (...)

## Ideas to obtain 12VDc from 400VAc

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.

## drop voltage of flyback konverter

who knows the how much drop voltage flyback converter or curve current vs voltage when loaded......

## High voltage low current DC

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.

## Did anyone help me design a 220V - 3.3V (15A) flyback?

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.

## Need to help about the design power device

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 (...)

## [need] CTX PR705F Monitor Schematics

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. (...)

## Req:HV power supply design guide

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 (...)
