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. |
