What is a coupling transformer

The magnetic transformer can sometimes be used to provide DC isolation between circuits but IMO the term coupling transformer is most often used when the device is used for changing the impedance levels Two main applications of this property are tube audio amplifiers and high power tube RF emitters used in Radio and TV broadcasting...

What is an isolation transformer Physics Forums

Aug 20 2011 0183 32 A transformer is an isolation transformer if the windings have only magnetic coupling between them However using this expression also implies that isolation is a function of the transformer You could convert from 220 volt mains to 110 volts by having a center-tapped winding or you could have two...
