摘要： An integrated circuit (IC) includes a first resonator circuit that includes: a first switching device that connects and disconnects a supply voltage to and from a first node; a first inductor that is connected between the first node and a first ground potential; and a second inductor that is connected between the first node and the first ground potential. The IC also includes a second resonator circuit that includes: a third inductor that is inductively coupled to the first inductor across an isolation barrier and that is connected between a second node and a second ground potential; a fourth inductor that is inductively coupled to the second inductor across the isolation barrier and that is connected between the second node and the second ground potential; and a second switching device that connects and disconnects the second node to and from a load. The second ground potential is different than the first ground potential.

摘要： A system includes a first galvanic isolator, a second galvanic isolator, a sensor, and a monitoring module. The first galvanic isolator includes a first electrical insulator. The second galvanic isolator is connected in series with the first galvanic isolator and includes a second electrical insulator. The sensor generates a first output signal based on an electrical characteristic of one of the first and second electrical insulators. The monitoring module, based on the first output signal, selectively generates a signal indicative of a failure of at least one of the first and second electrical insulators.
