Abstract:The influence of the secondary path parameters of the transformer active noise reduction system on the noise reduction effect is studied in this paper, and the calculation method of the secondary path delay is proposed. In this paper, based on the filtered-x least mean square (FxLMS) algorithm, an experimental system for transformer active noise reduction based on TMS320C6748 digital signal processor (DSP) is built, and the experimental results of transformer active noise reduction under different secondary path delays are compared. The influence of secondary path delay on the noise reduction performance of transformer active noise reduction system is verified.
