how to make a bridge (full wave) rectifier with 4 diodes

LINKS TO POWER SUPPLIES ARE IN THIS TEXTBOX.The video shows how to make a bridge (full wave) rectifier with 4 diodes. The flipped circuit is (of course) nothing new, but sometimes this insight can help when you read schematics. The + and - from the circuit "float", as long as there is no connection to ground. The choice which potential must be on ground ( + or -) is given by the properties from the electronic components and the electronic circuit. This is e.g. explained in my book "Schematics 2, audio amplifiers and loudspeaker boxes" (author Ko Tilman, ISBN 978-1-4475-7336-4). The efficiency from the bridge rectifier is good, all the energy from the AC transformer can be pulled out because both parts ( + and -) of the sine wave are rectified. The hum level is rather low, though still a problem for many audio circuits. A filter capacitor from 4700 uF is often used and gives (in many/most cases) enough suppression of hum. More info about home brew power supplies and hum suppression in my book "Schematics 1". It is easy to make a bridge rectifier yourself with 4 identical diodes. When you bend them in the showed shape they can be mounted on a small piece of aluminum (heatsink), glue them to the aluminum with polyester resin, mixed with plaster, and hardener. This has sufficient qualities to drain the heat to the aluminum.

Important: to find all the links to the (+/-700) video’s on my YT Channel, select, in the comments section, “NEWEST FIRST” My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there. https://www.lulu.com/shop/search.ep?keyWords=ko+tilman&type= There is an important video via which you can buy a document where I give links to many of my video’s, published between 2010 and 2018. Link is: https://youtu.be/XXRsA24NUE0 My books are also available via Barnes and Noble and via Amazon. Regarding all my video’s: I constantly keep them actual, so the original video’s with the most recent information are always on YouTube. That is the source, and search there. When my video’s are reproduced or re-edited on other websites/channels you can not (!) be sure about the original content (=really working electronics) and important adaptations to the circuits. Be aware of that, I saw on the internet my circuits reproduced in a poor or even not proper way. I can not help that, sorry. Update 1 June 2019.
