3-phase AC generator based on paper:
http://www.wseas.org/multimedia/journals/circuits/2014/a405701-233.pdf

f = sqrt(3)/[2pi(R)(C)]=50Hz
R= R1+R2=55K
C=C1=100n
R2/R1=2.1

Nice. The top diode of each pair does not seem to do anything. No current through them, and when I removed them, circuit behaved the same. What is the intended purpose for these?

Hi. Is the same diagram in the paper. It was practically copy and paste. But if you put two 10V zener connected Anode-anode obtain 10Vpp at the outputs. Actually is 1Vpp.

All OpAmp inputs have to be swapped to work as inverting amplifier with diode soft clipping. Soft clipping is used to get an acceptable THD. Without soft clipping it would do it hard at supply rail limits and cause bad THD.
