<p>An integrated magnetic filter inductor having series and common mode windings includes a magnetic core (44) having a first leg (46), a second leg (48), and a third leg (50). The legs are connected to each other with bridging structures (52, 54, 56, 58). Common mode windings (64, 66) are wound about bridging structures (52, 54) with the same dot polarity. Common mode windings (68, 70) may be wound about the bridging structures (56, 58) with the same dot polarity. A primary winding (62) may be wound about the second leg and induces a flux into the magnetic structure (44). Each of the common mode windings (64), (66), (68) and (70) has a leakage inductance associated therewith. The leakage inductances and the common mode inductances are magnetically isolated from each other and from the series inductance of the primary winding (62). A second primary winding comprised of windings (75) is wound about the first leg (46) and winding (77) is wound about the third leg (50). The secondary primary winding is magnetically isolated from all other windings. <IMAGE></p> |
