US Patent Issued on Oct. 20 for "Reduction of electromagnetic interference using random finite frequency set pulse-width modulation" (Canadian Inventors)

ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,771,275, issued on Oct. 20.

"Reduction of electromagnetic interference using random finite frequency set pulse-width modulation" was invented by Mostafa Abarzadeh (Cote Saint-Luc, Canada) and Simon Caron (Outremont, Canada).

According to the abstract* released by the U.S. Patent & Trademark Office: "As more power electronics apparatuses use fast switches, such as silicon carbide (SiC) or gallium nitride (GaN) switches, to improve the efficiency and reduce switching losses, significantly higher electromagnetic interferences (EMI) are generated as a result. While techniques of random pulse-width modulation (PWM) have been developed to reduce this increased EMI, the use of such techniqu...
