Burning Amp BA-3b (Balanced)

Simple to understand and remember


V peak is:

V peak = V peak to peak / 2


Average power is:

P av = V peak * V peak / 2*R load.


Bridging (or balancing) doubles Vpeak


No need to play with square root of two terms as at the end we square them which gives the 2*Rload term

I have a general rule that works for balanced and bridged amplifiers. I think it helps avoid the confusions that develop...snip

A pair of amplifiers arranged in bridged topology deliver double the power into double the load impedance...snip


and i cant thank you enough for supplying me with that rule when i asked for clarification via PM, when i needed some help parting the smoke that surrounds the subject. it was inline with what i had thought I understood, but everyone has a different way of explaining bridging and its effect on power into various loads. there is a lot of confusion even among people who know better and the above cuts through all that.

yes simple in isolation, my initial confusion arose from where 72v pk to pk was coming from with 36v pk to pk usable voltage from a single bipolar supply, but a good look at the schematic at point of load helped that.... then it was redface time

sqrt*2 or sqrt(2) is the shorthand in text isnt it? i was puzzled by how to do that too with ascii but remembered seeing it written this way and confirmed by natonrice

haha too late
ZM nvm about Pi, sqrt*2 is just as irrational so easy to confuse, particularly when there is probably maniacal glucose fueled children running around everywhere
