Power electronics lab » Pulse 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 : 1 fashion to couple a pair of thyristors. In given experimental board it is in 1 : 1 form.
