Abstract
An isolator circuit according to the present invention includes a first isolator, an AD converter, and a second isolator. The first isolator is configured to galvanically isolate a first terminal and a second terminal from each other. The first isolator receives an input pulse signal and outputs an output pulse signal to the second terminal. The AD converter is configured to output a digital signal corresponding to a duty ratio of the output pulse signal. The second isolator is configured to galvanically isolate the second terminal and the third terminal from each other. The second isolator is configured to receive the digital signal and outputs a feedback pulse signal to the third terminal.
