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
