Diagnosing resonant circuit involves comparing measured current with defined current corresponding to current for intact circuit at defined time, diagnosing current deviation above threshold as fault

摘要

The method involves measuring the current in the resonant circuit after a defined period corresponding to the time for an intact circuit to settle following the application of a voltage to the resonant circuit, comparing the measured current with a defined current corresponding to the current for an intact circuit at the defined time and diagnosing a deviation between the current values above a threshold as a fault. AN Independent claim is also included for the following: (a) a circuit for diagnosing a resonant circuit with at least one capacitor and at least one transmission coil.
