ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,395,164, issued on Aug. 19, was assigned to Mitsubishi Electric Corp. (Tokyo).
"Switching element drive circuit" was invented by Kazuaki Hiyama (Tokyo).
According to the abstract* released by the U.S. Patent & Trademark Office: "In the present disclosure, a buffer outputs a gate drive signal indicating the same logic level as an element control signal, and an inverting buffer outputs a base drive signal indicating the opposite logic level to the element control signal. The resistance is interposed between the output of the buffer and the gate of an IGBT. A PNP bipolar transistor has its emitter connected to the gate of the IGBT and its collector connected to reference potential. A di...
