  • Patent number: 10313162
    Abstract: The embodiments described herein provide communication devices and methods that can facilitate communication between galvanically isolated systems. Specifically, the embodiments facilitate communication to a galvanically isolated system that is shut down without requiring that this shutdown system consume its own power while it is shutdown. To facilitate this, the communication devices and methods provide a wake-up device on the side of the shutdown system and facilitate the transfer of power across the galvanic isolation to the wake-up device when communication to the shutdown system is needed. With the wake-up device powered using power that was transferred across the galvanic isolation, the wake-up device can perform the actions needed to wake up the shutdown system, and can thus facilitate communication between the galvanically isolated systems. Thus, communication between galvanically isolated systems is facilitated without requiring that the shutdown system consume its own power during shutdown periods.
