Abstract
An impedance regulator system and method which offers a large effective high-frequency block to isolate RF signals transmitted on power lines is presented. High-current inductors in series are inductively coupled over the RF band to physically smaller, low-current coupling inductors. The coupling inductors induce a degenerative or canceling at RF frequencies in the high-current inductors, resulting in the effective inductor increase and hence higher impedance over the RF band.
