摘要:
A magnetic interface circuit (100) includes a pair of channels (101, 102) and an absorb network (3). Each channel includes a 3-wire common mode choke (2) having a middle tap (21), and an isolation transformer (1) connected with the 3-wire common mode choke. The isolation transformer has a primary winding (11) and a secondary winding (12) each having a pair of first output taps (111, 121) and a first center tap (13, 14). The absorb network includes a bridge rectifying circuit (4) adapted for converting an electrical current. Each bridge rectifying circuit has a pair of input taps (45, 46) each connected with corresponding center taps of the isolation transformers, and a pair of output taps (47, 48).
