AI Technical Summary
In existing technologies, the data reliability of electronic devices is affected when there is an abnormal power outage, and uninterruptible power supply devices increase power consumption, footprint, and cost, and cannot effectively cope with instantaneous power outage scenarios for high-speed data interaction.
Design a functional module that includes a circuit board and a backup capacitor in a cutout slot. The cutout slot reduces space occupation, and a metal layer is set on the circuit board for electromagnetic shielding. The backup capacitor provides temporary power to the core unit when the functional module is powered off, including a redundant design of main backup capacitors and auxiliary backup capacitors.
It enables rapid response during sudden power outages, avoids data loss, reduces the space occupied by the circuit board, adapts to high-density layout requirements, and takes into account electromagnetic interference protection.
