US Patent Issued on April 14 for "Fault current bypass based solid state circuit breakers and active clamping snubbers for DC circuit breakers" (Pennsylvania Inventors)

ALEXANDRIA, Va., April 15 -- United States Patent no. 12,603,649, issued on April 14.

"Fault current bypass based solid state circuit breakers and active clamping snubbers for DC circuit breakers" was invented by Fei Lu (Wynnewood, Pa.), Hua Zhang (Philadelphia) and Reza Kheirollahi (Philadelphia).

According to the abstract* released by the U.S. Patent & Trademark Office: "A thyristor-based dc solid state circuit breaker (SSCB) named Y-type includes a new complementary commutation circuit including a capacitor-capacitor pair, which features three advantages. First, a fast commutation is achieved using a countercurrent pulse injection by the capacitor-capacitor pair structure. Second, metal-oxide varistors (MOVs) are disconnected from the ...
