FPGA-based solid-state power controller inverse time over-current protection device

The invention discloses an FPGA-based solid-state power controller inverse time over-current protection device, mainly solving the problems that the existing time over-current protection device is poor in reliability, high in power consumption, low in accuracy and poor in strong electromagnetic interference resistance. In the invention, a clock management module, a multiple data register group module, an FSM control module, an inverse time over-current protection module and an output control module are arranged in the interior of FPGA; wherein the multiple data register group module receives an FSM control module address signal and outputs data to the FSM control module which judges the data, the judged data enters the inverse time over-current protection module, result calculated by the inverse time over-current protection module is returned to the FSM control module which compares the returned data, the comparison result is sent to the output control module which outputs a control signal to an outside circuit, and the clock management module provides a system clock for all modules. The invention has the advantages of high accuracy, strong reliability, strong electromagnetic interference resistance, low power consumption and the like.
