Patent number: 12009760Abstract: An electronic device may include an inverter. The inverter may convert direct current (DC) power to alternating current (AC) power. The inverter may use a clock signal at a given frequency to output corresponding alternating current signals at the given frequency. The inverter may receive a dithered clock signal that is frequency dithered using a modulating signal. The dithered clock signal may have at least three different frequency levels during a repeated cycle of the modulating signal. The at least three different frequency levels may include a fundamental frequency, a first frequency that is lower than the fundamental frequency, and a second frequency that is higher than the fundamental frequency. The dithered clock signal may be, during the repeated cycle of the modulating signal, at the fundamental frequency for fewer total periods than at the first frequency and for fewer total periods than at the second frequency.Type: GrantFiled: June 26, 2023Date of Patent: June 11, 2024Assignee: Apple Inc.Inventors: Sujeet Milind Patole, Cheung-Wei Lam, Mahmoud N Mahmoud
