can you explain for SMPS in detail too? Thank you for the explanation!

Thank you everyone for alert! i will study and learn before practical!

Thanks for the image!

What is the safe way? Can I put transformer between AC and circuit so it will step down voltage?

Can anyone suggest value for L and C to reject 60Hz frequency? I did google but all is about only diagram.

Got it! Thank you all for the responses. How to calculate voltage that comes after this filter circuit? (Input is AC mains.) I am looking for formula or method. Thank you!

Hi Baluncore, Thank you for the input. I wanted to try the other way. With transformer and bridge rectifier with storage capacitor is common method. I want to try only.

I am very new in this field (2nd year) so I don't know much. If I will remove 60Hz successfully then I will feed to Voltage regulator and try to get some specific voltage out of it. (for ex. 12V out of voltage regulator.) Thank you!

Let's think the other way. How can I make LC-LPF filter that can reject 60Hz? (not considering this for AC signal.) Assume this is a frequency of some signal.

Rectifier can convert AC into DC but I am not looking for that. In other words, I am not looking to convert AC into DC by LPF. I want to make filter that gives me close to zero frequency when I applied AC (mains). I want to chop AC frequency to none (close to zero). Thank you!

Hi All, I am looking to design LPF with Inductor and Capacitor that can reject 60Hz frequency. I tried on google about the same but did not get an idea. Basically, I am trying to do is this, Incoming mains (AC Signal) has 60Hz frequency and I wanted to make it like a DC (close to DC) which...

Hi Dave, just trying to simulate something odd. I wanted to see what if I pass DC into bridge rectifier. (As we know that AC will convert into DC.) Yes, for AC is normally 110/220V (That number was just to cover +/-20% margin.)

bridge rectifier design... Can I use the same bridge rectifier for AC as well for DC voltages? My AC mains is regular 265Vac and DC is 40Vdc. How should I choose bridge rectifier? (In other words, what are the parameters I need to check while selecting diodes for bridge rectifier?) Thank...

Hi sophiecentaur, I respect your post. I should stop discussing at this point as I am not moving in proper direction. Thank you All for spending time for my post. pj

Hi Dave, As I said, few folks told me that there is no sensing circuit is required and for that please see post #6. I am not here to prove anything. I am only looking for engineering solution/help. Thanks, pj
