Abstract
A method for determining a remaining useful lifer of a switch is provided. A position of a switch in a converter is determined. A switching sequence for the converter is determined based on the position of the switch. The converter is operated based on the determined switching sequence. An ON-state voltage across collector and emitter of the switch is measured. A remaining useful life of the switch is determined based on the measured ON-state voltage across collector and emitter.

A method for determining a remaining useful life of a switch, the method comprising:
- determining a position of a switch in a converter;
- determining a switching sequence for the converter based on the position of the switch;
- operating the converter based on the determined switching sequence;
- measuring an ON-state voltage across collector and emitter of the switch;
- and
- determining a remaining useful life of the switch based on the ON-state voltage across collector and emitter.
A computing device comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- determine a position of a switch in a converter;
- determine a switching sequence for the converter based on the position of the switch;
- operate the converter based on the determined switching sequence;
- measure an ON-state voltage across collector and emitter of the switch;
- and
- determine a remaining useful life of the switch based on the ON-state voltage across collector and emitter.
A non-transitory computer-readable medium storing instructions that, when executed, causes a processor to perform operations, comprising:
- determining a position of a switch in a converter;
- determining a switching sequence for the converter based on the position of the switch;
- operating the converter based on the determined switching sequence;
- measuring an ON-state voltage across collector and emitter of the switch;
- and
- determining a remaining useful life of the switch based on the ON-state voltage across collector and emitter.
