A Circuit Design to Protect Current Surge for Unmanned Factories

With the increasing dependence on precision electronic equipment, self-protection becomes essential. The protection circuits usually used in the past include fuses and circuit breakers. However, these circuits are not enough for the current need of high-speed protection and automatic engineering logic. In this paper, we develop a new high-speed protection circuit, which is over 20 times faster than the traditional circuit and has the ability to self-recovery when any failure occurs. Thus, there is no need to do manual restart and it also meets the future needs of precision electronic equipment protection. This design provides more convenience and reliability for the unmanned manufacturing factory in the future.
