Abstract
Systems, methods, techniques and apparatuses of high current protection are disclosed. One exemplary embodiment is a power system comprising a solid-state circuit breaker including a solid-state switching device, an energy dissipation branch, an assistive branch, and a controller. The energy dissipation branch is coupled in parallel with the solid-state switching device and includes an energy dissipation device. The assistive branch is coupled in parallel with the solid-state switching device and includes a resistor, an inductor, and a galvanic isolation switching device coupled together in series. The controller is configured to determine the solid-state circuit breaker is conducting a high magnitude current, select a continuous current limiting mode or an intermittent current limiting mode, and operate the solid-state switching device based on the selected current limiting mode.
