Watchdog scheme for monitoring a power electronic inverter and determining a manner of operating a load

In one example embodiment, a circuit includes a first sub-circuit configured to generate first data corresponding to a frequency and a duration of overloading of a transistor in the inverter, and a second sub-circuit configured to generate second data corresponding to a rate of rise of a voltage and...

Beschreibung
Zusammenfassung:	In one example embodiment, a circuit includes a first sub-circuit configured to generate first data corresponding to a frequency and a duration of overloading of a transistor in the inverter, and a second sub-circuit configured to generate second data corresponding to a rate of rise of a voltage and a peak voltage value of the transistor in the inverter. The first sub-circuit and the second sub-circuit are configured to respectively provide the first data and second data as outputs to a controller for analyzing a manner in which a load coupled to the inverter is driven.
