I came across an interesting article recently with some information I hadn’t seen yet, so I figured I would share it here. I may be a little behind the times, but I hadn’t looked this closely into power circuits in quite some time.
It seems that there is an improvement over the bridge rectifier, which involves using MOSFETs instead of diodes. There is a little bit of added complexity because it uses a few extra components (resistors and diodes) to trigger the MOSFETs. Since a bridge rectifier can be implemented on a single chip, it still has the benefits of cost and simplicity.
Here’s the article where I found out about it. Definitely something I plan on experimenting with.
