apply zobel to bridged amplifier
PhilW have a wery good question.
How do one apply a Zobel network to a bridged amplifier ??
There are two ways to go:
A. A zobel-network to ground for each of the "amplifier-arm" in the bridged amplifier. This makes sense and will for sure work.
B. Just applie the zobel-network between the two "HOT" amplifiers that makes up the bridged amplifier. This zobel-network will have no reference to ground.
This saves you one "zobel-network" and should in teori work just as well. Many class-D amps and other amplifier topologies that are "born" with bridged ouput seems to take this road.
However, I have never seen any explanation or test of solution A compared to solution B.
I have used B witch seems to work fine.
If someone have expirence or pros and cons of one compared to the other, please let us know.
