Fault current limiter with fault checking system for power electronics and bypass circuit

摘要

The fault current limiter may include a current limiting leg for transmitting a first current and a control leg for transmitting a second current in parallel with the current limiting leg. The control legs may include a plurality of power electronics modules arranged in electrical parallel with each other, and a bypass power electronics module arranged in electrical series with the plurality of power electronics modules. The control leg may further include a plurality of current monitors arranged in electrical series with the plurality of power electronics modules and the bypass power electronics module, and at least one triggering circuit, wherein the plurality of current monitors are at least one Wherein at least one triggering circuit is coupled to at least one of the plurality of power electronics modules and the bypass power electronics module.
