Why you need ANALOGUE SIGNAL? You can make 3 sin signals with 120 degree. And use any type of "analogue signal" just as feedback. For control amplitude or frequency.

analogue signal is part of the task.
but that is not an issue...the prob is the svpwm implementation on an fpga.
can you explain me in detail what you meant by make 3 sin signals.........

The 3 sin signals can be generated by using 3 look up tables with pre-calculated sin values.
To control the output frequency, all you need to do is to control the speed of the address sequencer (basically a counter)

can you please explain me what you have typed in as its still very unclear to me.
