Abstract
A method for detecting a performance degradation of a fan in a power converter is disclosed. The method includes monitoring a speed of the fan and detecting the performance degradation of the fan based, at least in part, on the monitored speed. The method further includes generating a warning signal after detecting the performance degradation of the fan. According to another aspect, a power converter includes a fan and a processor operably coupled to the fan for monitoring a speed of the fan. The processor is configured for detecting a performance degradation of the fan based, at least in part, on the monitored fan speed. The processor generates a warning signal after detecting the performance degradation of the fan.
