Abstract: A system and method for monitoring the state of health of a power electronic system. Data representing an initial expected temperature of the circuit element and an initial value of an electrical parameter of the circuit element is obtained. An electrical pulse is applied to the circuit element to heat the circuit element. After the electrical pulse decays to a predetermined value, the electrical parameter of the circuit element is sensed and a subsequent value of the electrical parameter is obtained. A subsequent temperature of the circuit element is estimated based on the initial expected temperature of the circuit element, the initial and subsequent values of the electrical parameter, and the predetermined value of the electrical pulse. Based on the subsequent temperature, the signal that indicates whether the circuit element is operating as expected is generated.

Abstract: A fault detection circuit and method for monitoring a power converter system to identify faults. The detection circuit includes two comparator circuits each having one input connected to the dc bus of the power converter system and responsive to the voltage spikes that occur as a result of faults. The other inputs of the comparator circuits are respectively connected to first and second sources of reference voltages having preset limits. The outputs of the two comparator circuits are combined on an output lead, and a fault signal will be produced on the output lead when the voltage spike on the dc bus exceeds the limits.
