The synchro transmi tter / receiver
demonstrator unit is designed to study of
remote transmission of position in AC servo
mechanisms. These are also called as torque
transmitter - receiver. The unit has one pair of
transmitter - receiver synchromotors, powered
by an isolated ac inbuilt supply.
Power electronics labPulse transformer & optocoupler technique |
Pulse transformers are used to couplea trigger pulse generator to a thyristorin order to obtain isolation between twocircuits. Generally these are woundupon a ferrite cored bobbin, in 1 : 1 ratio( NP: NS), to couple one thyristor, or 1 :1 : 1fashion to couple a pair of thyristors. In givenexperimental board it is in 1 : 1 form. |
