The present invention provides an active inductive impedance enhancement circuit applied to a power line path. It utilizes a closed-loop control technique to detect residual high-frequency signals on the power line and generates a compensation current injected into the secondary side of the main inductor accordingly. The invention actively suppresses high-frequency current flowing through the main inductor, thereby significantly enhancing its impedance against high-frequency noise.
