Hello,
Unfortunately, I was raised in the digital age and dont have a great grasp of Synchros. I am trying to develop a replacement to a synchro amplifier that we use for a piece of military equipment. From me research I have learned quite a bit about the Synch amps but I still have some questions.
The input is a resolver 6V 60Hz (and another amp at 400Hz). This voltage then needs to be matched to the input of a Scott T transformer(I think). This is then turned from sin(x) and cos(x) to S1 S2 and S3. Does S1 S2 and S3 come out at 90V out of the Scott T? I think I have it correct up to there except the voltages on S1-S3. Now I would personally send these three AC waves to a power amplifier (or a voltage amplifier first if S1-S3 are lower then 90V AC). Then after these power amplifiers and some circuit to detect a rotor lock, can I connect it to an output, or am I missing something. Other designs I have looked at (CCC,CSI...etc.) Seem to have a pulsed (pwm?) power supply that uses the boats power as a reference. What is this thing for? Is it necessary?
Sorry for all the questions, and thank you for the help, Matt
