I agree they are the same. The bottom one is not a power rectifier bridge - it is a ring. A rectifier bridge has one node with two cathodes and one node with two anodes. In the image above, all nodes have one anode and one cathode.At first glance, this is just two ways to draw the same thing, but a power rectifier bridge will have problems with high frequencies.
It will not work. In a diode ring, no two cathodes or anodes are connected. In a bridge there is one common anode connection and one common cathode connection. Signal flow through the two devices is significantly different.i'm curious about what would happen if a diode bridge were substituted. has anyone experimented with this?
