NEED HELP FOR MY PROJECT !

[DejoBleyo]

Hi everyone, i need some tips for my project which is building custom power regenerator (12V DC PSU,12V Inverter and capacitors with inductors). I just want to know how many inductors and capacitors should i add and what type for worst case scenario (harmonics and emi) for filtering minimum 100hz to at least 1Mhz if not more. I know capacitors should be in parallel, can inductors be in parallel too or should they be in series like on positive only ? Please help i have very dirty electricity and i dont know what exactly frequency is the problem and i want to filter it all if its possible so i dont need to worry if my new pc is gonna get damaged someday so i want it to make it as good as possible. I made my own scheme but its only an idea so you know what i mean.

Inductors also can be in patallel, its common mode choke. I think filtering from 100Hz is practically unrealistic and impractical. If you want to affect well on frequencies from 1kHz, then you need materials like amorphous strip (nano crystalline strip) especially if you are going to be working with high A (amps). Good inductance and max current apply. You can get to ~100 of mH and max current of ~10A, I have some of those 120mH 6A, but they are in AC with X2 10mkF capacitors (Ferrites of different materials cant do that). The frequency spectrum can be really wide, there is any of kHz and MHz (1-1000) shit especially on !!neutral!!. If you want to exactly get compleatly nuts with filtering, then shield the DC filter components and position them right for high frequencies. Before all this filtering, I would recommend isolate N and remove G (protective earth). In your DC PSU can be galvanic coupling between N-G and - of DC. Noise also can pass through parasitic capacitances, that is usually what happens. Grounding (TT, IT) is like a huge lifesaver in case of filtering out all interference. (Since jitter will affects the proper functioning of DAC and ADC, whole sound becomes truly dead, but even with a hot connection of ground wire everything gets better, audio is isolated from the PC case) Ensure good contact between everything. If it is not fiber connection to your router (I mean if it is connected with an RJ45 twisted pair), thats a problem. Your hardware (and windows) cannot break unless the correction mechanisms in PCIE and so on have gone into a state from which they will not come out even if you fix the electricity problems, but anyway it will be better. Resetting BIOS and plugging in and ous PCIE devices and RAM may help. Bad electricity can cause capacitors to suffer and lose their properties, so filtering will be worse, but as practice shows, in places without the problem people play on full shit PSUs with high ripples and everything works good.
