I found a couple of old bridge rectifiers. After reading some docs and tutorials about reverse polarity protection decided to give them a try. The problem is nobody offered a solution against the voltage drop (and the power loss) after the rectifier, which is usually mounted at the load side not at the supply side.
What is the way to avoid this drop - using higher voltage as input or additional circuit to overcome this at the load side?
Note that I chose this way of protection so the protected device will continue to work
