Hi,
I am trying to compare the magnitude of the DC outputs of two full
bridge rectifiers.
The two rectifiers are getting inputs from two different sinusoidal
sources of frequency 80 KHz who are in phase but could have different
amplitudes. Based on the magnitude of the DC output, I have to decide
which bridge will be providing power to the load as shown in the
link.
I posted the circuit at the following link to compare the two output
voltages

Am I on the right thinking process?

If you remove D1 and D2 and connect the outputs of the two bridges
together, then when the output voltage of the upper bridge is higher
than the output voltage of the lower bridge, current out of the bottom
bridge will be blocked and the load will be fed by the upper bridge.
Conversely, if the output voltage of the lower bridge is higher than
that of the upper bridge, the upper bridge will be cut off by the
lower bridge and the load will get its current from the lower bridge.
Plus, you won't have to suffer the losses in D1 and D2.
How would you compare the current from each bridge?

Who cares?
Melissa the OP, yes? (Emphasis mine):
"I am trying to *compare the magnitude of the DC outputs* of two full
bridge rectifiers."
"Based on the magnitude of the DC output, *I have to decide
which bridge will be providing power* to the load as shown in the
link."
"I posted the circuit at the following link *to compare the two output

All she wants is to have the bridge with the highest output voltage
drive the load.
I didn't get that from her post.
