Yes, I do have a transducer that acts as a load on the transformer output, vibrating with the signal from the transformer.
And just want to clarify some confusion that I have regarding the transformer with a uni-directional pulse that you mentioned, did you mean that for that kind of transformer, it will always need some DC current in the primary before it can start transmitting its power to the secondary? If that is the case, anyway I can get around that? Or probably going to a bi-directional pulse transformer or something?
