Patent 11611340 was granted and assigned to Mitsubishi Electric Corporation on March, 2023 by the United States Patent and Trademark Office.
A drive circuit includes a second drive circuit that drives a semiconductor switching element in a case where a pulse width of a corresponding signal is determined to be larger than a second threshold, and a timing adjustment circuit that adjusts a timing at which the second drive circuit cooperates with a first drive circuit to drive the semiconductor switching element during a turn-off period of the semiconductor switching element due to drive of the first drive circuit.
