US Patent Issued to TMEIC on May 12 for "Voltage control apparatus and voltage control method" (Japanese Inventors)

ALEXANDRIA, Va., May 12 -- United States Patent no. 12,627,144, issued on May 12, was assigned to TMEIC Corp. (Tokyo).

"Voltage control apparatus and voltage control method" was invented by Mohammad Bani Shamseh (Tokyo) and Haiqing Li (Tokyo).

According to the abstract* released by the U.S. Patent & Trademark Office: "A voltage control apparatus, when a voltage drop of an output voltage of an inverter is equal to or larger than a threshold, calculates first virtual impedance using various variables, calculates, such that an output current of the inverter does not exceed a rated value, second virtual impedance to be temporarily added to the first virtual impedance, calculates a virtual active voltage and a virtual reactive voltage by multi...
