INDUCTOR ASSEMBLY AND POWER SUPPLY SYSTEM USING THE SAME

An inductor assembly (1) is disclosed comprising a magnetic core (2) with a center leg (3) and a number n of phase legs (4), wherein n is an integer and n>1, each phase leg (4) being magnetically connected to the center leg (3) by an upper bridge (13) and a lower bridge (13) to form a magnetic main loop, a midpoint (5) of the phase leg (4) being magnetically connected to a center point of the center leg (3) by a shunt element (6) comprising a gap (7). Each phase leg (4) further comprises an upper inductor coil (8) disposed on an upper phase leg section (10) located between the midpoint and theupper bridge (13) and a lower inductor coil (9) disposed on a lower phase leg section (11) located between the midpoint and the lower bridge (13). Alternatively, the upper and lower inductor coils (8, 9) are disposed on respective upper and lower bridges (13). The upper inductor coil (8) comprises a first terminal (20) and a second terminal (21), and the lower inductor coil (9) comprises a thirdterminal (22) and a fourth
