Abstract
A circuit for providing damping in an electromagnetic interference (EMI) filter with an inductor-capacitor (LC) circuit, includes at least one capacitor connected to receive a common-mode current from the LC circuit; a current sensor that senses the common-mode current; a linear amplifier that amplifies the sensed common-mode current; and a power amplifier that receives the amplified sensed common-mode current and outputs a voltage which creates a damping impedance for frequencies of the common-mode current less than a threshold frequency and absorbs the common-mode current for frequencies greater than the threshold frequency.
