“The two main sources of supraharmonics that have been identified are power-electronic converters with active or passive switching (non-intentional emission) and transmitters of power-line communication (intentional emission).”

“The term "supraharmonics" was first introduced in 2013 during the summit entitled "IEEE Power & Energy Society" to indicate any kind of voltage and current waveform distortion within the range of frequencies from 2 to 150 kHz.”

“Characteristic examples of devices that have been associated with acoustic noise resulting from supraharmonics are battery chargers for electronic equipment such as personal computers and smart phones.”
