How to make a power conditioner

stolenband · 27th March 2011, 11:01 PM

Hello to all. I am trying to make a power conditioner that is able to keep different appliances in the building and down the street from causing noise in my amps. I wOuld like one that could split to four outlets, then condition each one separately to prevent noise from one amp to another. I have a couple battery backups but those don't work to keep interfearence from lights or or amps at bay.

What you are talking about is power line filters. You can probably buy them, but if you want to make your own you first need to specify the requirements. Then you need to design the filters. You probably need both differential mode and common mode filters.

I also have no knowledge of high voltage electronics. Rather way. I want these to isolate the circuit to the amps from having any line interference. I just want to make one. Is there any cheap way and what devices can I get parts from/what pats do I have to buy.

somebody has to volunteer to explain how to do one's own research.

Normally that sort of topic (how to research a project) is taught in school.
I am beginning to believe that some/many of our Members opted out of school for whatever were their reasons.

DIY mains filtering is not the safest route to an understanding of high voltage electronics. Best option is to buy packaged filters, and put them in a grounded metal box. The alternative is to do some reading about LC filters and mains safety, rough out a design, then put it here for us to comment before it is built.
