Abstract
A method of monitoring health of a power semiconductor device includes: determining a steady state loading of the power semiconductor device; when it is determined that the power semiconductor device is under a steady state loading, monitoring a case temperature parameter relating to a temperature of the case of the power semiconductor device over a predetermined period, derive a normalised parameter from the monitored case temperature parameter and determine the health of the power semiconductor device based on the normalised parameter.
