I am trying to get an isolated armature voltage feedback by driving a transformer in push-pull configuration.However I do not an output till the voltage reaches 1.4V, due to the bridge rectifier.

What is the technique generally used to obtain isolated armature volateg feedback ?Is opto-isolation used in such an application ?

Any suggestions ?

Thanks.

Try with Shottkey diode ,
I have seen a DC PT used for the same in Siemens drive.I will find out the exact diagram and let you know.
