US Patent Issued to NXP USA on Nov. 25 for "Multiple and sinusoidal pulse width modulation for wireless charging" (Chinese Inventors)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,160, issued on Nov. 25, was assigned to NXP USA Inc. (Austin, Texas).

"Multiple and sinusoidal pulse width modulation for wireless charging" was invented by Dechang Wang (Suzhou, China), Wei Cao (Suzhou, China) and Xiang Gao (Shanghai).

According to the abstract* released by the U.S. Patent & Trademark Office: "Transferring wireless power using a multiple pulse width modulation M-PWM driver signal includes generating the multiple PWM driver signal such that the pulse width varies in accordance with the magnitude of a periodic modulating curve. The M-PWM driver signal adjacent a zero-crossing of the periodic modulating wave is modified by reducing an interval between the zero-cros...
