N2 - The LC power filter is the filter with the longest application history. It has been applied in the 1920s and is still widely used in various fields. When the LC low-pass filter works, the working current of the power supply must pass through the inductance of the filter. The larger the power supply current is, the greater the power the inductance bears, the larger the volume and weight of the filter, and the greater the environmental vibration noise. The application scope of the low-pass EMI filter is greatly limited; especially the occasions requiring high-power power supply. In order to overcome this problem, active filter technology, adaptive filter technology, etc. have been developed; The characteristic of the adaptive filter is a high-pass filter. When working, the power supply current does not pass through the inductance of the filter, which can transform the suppression of strong signals into the cancellation of weak signals. This paper focuses on the research work of adaptive active filter technology and adaptive passive filter technology.
