Abstract

An electronic device includes: an interface configured to receive telemetry information for one or more power semiconductor devices; and a data acquisition and processing unit. The data acquisition and processing unit may be configured to periodically update an estimate of a remaining lifetime of the one or more power semiconductor devices, based on the telemetry information collected during use of the one or more power semiconductor devices and received at the interface. The data acquisition and processing unit may be configured to adjust one or more operating parameters for each of the one or more power semiconductor devices that has reached a predetermined level of degradation as determined by the telemetry information. An electronic system that includes the electronic device is also described.
