Oh, i forgot about the caps...
Bad, bad, bad...
Yes. It is not easy. The problem with high value resistors is that they very ureliable. It happened to me a few times. It is very ugly when one fails.
Maybe half bridge. The forward has some other problems. I think, that half bridge is better.
I...
This is a bit scary :-|
Any ideas how it can be done ?
High value resistors are not an option.
If something screws up, there will be quite a bang and high voltage when i don't need it (Murphy's law :-D).
That is a good idea :-D
Then, i can use a ready design and just add the multiplier.
Can i take the feedback from the low voltage ?
Is it going to be a problem when i connect the multiplier ?
I have a nice design for a 0-50V 0-10A lab SMPS, but it is half bridge.
Well, this is a good idea, but is does not suit me.
I need a laboratory power supply.
It must be regulated and it must keep it's max. current at lower output voltage.
Yes. I know it is not simple, but i will try.
My problem is the way how to control it.
The transformer is not a big problem.
I...
Hi everybody and happy new year !
I need an adjustable power supply which goes from around 100V to 1KV at 500mA.
So, how do i achieve this ? I am going to use it as a laboratory power supply for vacuum tube electronics.
It needs to be reasonably simple (for more reliability) and cheap (I am in...
awww
nice idea for the primary sensing
it will be with CT-as you said the high quality resistors are expensive, and it will decrease the efficiency
i am going to produce custom power supplies,amplifiers,osciloscopes...*will use already tested schematics
this is why i want it to be low noise...
ok, so current transformer, but this is a low noise, high accuracy lab. smps-the CT is a bit inaccurate as i heard
can you draw what you mean for the feedback and relax network
ok
si8420's datasheet says that it can be used in smps feedback?
then it will be with optoisolator
or not isolated-will isolate it with gate drive transformer
i will absorb it somehow
any ideas
maybe active or lossles clamp
if i change these things, is it going to work
