AI summary

The proposed computer-implemented method has the following aspects: the load control transmits current temperature measurement data of the electronic component to the temperature regulation and temperature simulation systems; current load measurement data and temperature measurement data of the electronic component are also transmitted to the AI-based load prediction and AI training. Extending the service life is prioritized over immediate efficiency maximization, as service life has become a critical design criterion in all electronics. This is achieved through temperature regulation of the electronic component via load control and optionally active thermal management.
