Title:
SYSTEM AND METHOD FOR A PREDICTIVE SUPPRESSION OF ELECTROMAGNETIC INTERFERENCE OF POWER ELECTRONICS SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2023/031463
Kind Code:
A8
Abstract:
The suppression of electromagnetic interference (2) is to be improved for a device for suppressing electromagnetic interference (2) in power electronics systems (1). This is achieved in that the device comprises a digital counter-interference system (3), wherein the digital counter-interference system (3) comprises at least one interference predictor (12) and a counter-interference synthesizer (13). The interference predictor (12) is designed to detect at least one piece of information for predicting electromagnetic interference (2) of a power electronics system (1) and to additionally generate a prediction of the electromagnetic interference (2) and transmit same to the counter-interference synthesizer (13), and the counter-interference synthesizer (13) is designed to synthesize a matching counter-interference signal (14) on the basis of the prediction of the electromagnetic interference (2) of the interference predictor (12). The device additionally comprises at least one injector (16), wherein the injector (16) is designed to couple the synthesized counter-interference signal (14) into a complete system which is to undergo interference suppression. The invention also relates to a method for a predictive suppression of electromagnetic interference (2) of power electronics systems (1).
