Abstract
A network for connection between an AC power line and a DC power supply to isolate harmonic currents generated by the DC power supply from the AC power supply, the network employing at least one "resonator", which is connected across the input of a DC power supply, and at least one "reflector", which is connected to couple the input of the DC power supply to an AC power line. Each "resonator," includes the series combination of an inductor and a capacitor. At least some of the "reflectors" include the parallel combination of an inductor and a capacitor.
