The present invention relates to a differential mode electromagnetic noise injection network and an active electromagnetic interference filter. The differential mode electromagnetic noise injection network includes an injection piece and a differential mode loop. The injection piece is at least provided with a first injection end, a second injection end, and a differential mode electromagnetic noise component input end. The differential mode electromagnetic noise component input end is configured to input a differential mode electromagnetic noise component. The first injection end and the second injection end are connected to any two points that are connected in series in the differential mode loop in a one-to-one correspondence, and are configured to inject the differential mode electromagnetic noise component.
