3 phase sine wave generator

Hi
Does anybody have a three phase sine wave generator circuit with analog comonents?
Please post.
Thanks

3 phase sine wave generator circuit

What frequency? What phase angles? How much voltage and power?
 

three phase sine generator

hi
50Hz 120deg phase difference like tility power supply. Only test signal generation is required, May be 5Vpp.
Thanks

wave generator circuit

One way to generate a sine wave is to pass a square wave through a low-pass filter ..
The high-order harmonics will be filtered out, leaving only the fundamental; the higher the order of the filter, the purer the sine wave produced ..

And three square waves shifted by 120° can be easily generated using simple, small-foot-print microcontroller such as, for example, PICAXE-08 (8-pin) ..

I know this is not ANALOG solution, but you may consider also this option ..

Regards,

3-phase generator

Thanks
I was thinking of a ring counter with FF and shift registers and sync a function generator to follow the output of the same.
More ideas welcome
