The isolator with fast response time (10mSec) is typically used in feedback control system.

In input dc current is chopped by the chopper to convert it into high frequency ac signal. This signal is fed to an isolating highfrequency transformer. The ac output current from the transformer is rectified and filtered to obtain load independent dc outputcurrent. As the transformation ratio is 1:1 the output current is identical in value to the dc input current.
