1. A method of operating a wireless energy transfer system executed by a control processor of the wireless energy transfer system, the method comprising:

  • identifying a priority rank for each of a plurality of system faults, each priority rank representing an execution priority for a corresponding one of the system faults;

    monitoring the system for activation of faults, wherein the monitoring comprises;

    repeatedly executing a first control loop associated with a first fault having a first priority rank indicative of a high priority fault, the first control loop having an associated first execution time period T1; and

    repeatedly executing a second control loop associated with a second fault having a second priority rank indicative of a moderate priority fault, the second control loop having an associated second execution time period T2; and

    transmitting a signal to a power source controller in response to detecting that one of the first and second faults is active,wherein T2 is larger than T1 so that during a monitoring time period, the first control loop is executed more frequently than the second control loop; and

    wherein the signal is transmitted at a speed corresponding to the priority rank of the active fault.
