Abstract: The current invention is connected with the adaptive electromagnetic interference (EMI) suppression system that is aimed at reducing dynamic and broadband conducted noise in current electronic circuits. As higher frequency switching equipment, smaller printed circuit board (PCB) designs, ferrite beads, inductive filters, and shielding have become increasingly popular methods of passive EMI suppression, time-varying and non-stationary interference, such as that by power converter capacitors, has become difficult to alleviate by these conventional passive methods. The suggested system presents a smart closed-loop EMI suppression system continuously tracking conducted noise signals via an integrated sensing circuit. These sensed signals are then in real time processed using an embedded digital signal processing unit, which is able to perform spectral analysis to determine the dominant interference frequencies and their properties. According to the data under analysis, the system is dynamically formed in that the anti-phase signal with the same amplitude and phase properties is generated. This signal is actively added into the affected line which causes the destructive interference and effective cancellation of all unwanted noise components. The system is adaptive and it keeps changing its response in response to changes in pattern of interference in different conditions of operation. The architecture proposed combines sensing, processing and controlled signal injection into a small and energy efficient system, which is easily interconnected with the existing electronics. Compared to traditional methods of filtering on a static basis, the invention offers adaptive realtime EMI mitigation of signals, better signal integrity, system reliability, and electromagnetic compatibility (EMC). It is a scalable and smart invention that can be utilized in the next-generation electronic devices such as power electronics, automotive systems, communication equipment, and high-speed digital platforms.
