    • A compact magnetic power unit for a power electronics system The magnetic poser unit (100) comprises a magnetic core (10) including a first, a second and a third winding channels (2a, 2b, 2c) respectively arranged around a first, a second and a third crossing axis (A-A, B-B, C-C) orthogonal to each other, each of said winding channels (2a, 2b, 2c) being intended for receiving one coil wound around the magnetic core (10), each coil having at least one turn. The crossing axis (A-A, B-B, C-C) define orthogonal planes providing eight octants, each including a protrusion defining a protruding spacer (20), being spaced to each other by said winding channels (2a, 2b, 2c). The magnetic core (10) is a composed core formed by several different partial magnetic cores assembled together including two side partial magnetic cores (12), each including four protruding spacers (20). The magnetic core (10) further includes a through hole (30) housing a device for heat dissipation (50).
    • 用于功率电子系统的小型磁功率单元磁性贴装单元(100)包括具有第一,第二和第三绕组通道(2a,2b,2c)的磁芯(10) 分别围绕彼此正交的第一,第二和第三交叉轴(AA,BB,CC)布置,每个所述绕组通道(2a,2b,2c)用于接收缠绕在磁芯(10 ),每个线圈至少有一匝。 交叉轴(A-A,B-B,C-C)限定了提供八个八分圆的正交平面,每个八分圆包括限定突出间隔物(20)的突起,所述突起通过所述缠绕通道(2a,2b,2c)彼此间隔开。 磁芯(10)是由若干组装在一起的不同部分磁芯形成的组合磁芯,包括两个侧部分磁芯(12),每个部分磁芯包括四个突出间隔件(20)。 磁芯(10)还包括容纳散热装置(50)的通孔(30)。
