机载直流电源系统是全机系统及设备的重要供电装置，但同时其本身的直流控制和调压器件等会产生非常复杂的电磁发射，这些电磁发射满布于整个机身内部，其中的无线电设备特别是低频设备如无线电罗盘等会受到这些电磁发射的干扰。本文从发电机控制盒与直流发电机之间的互连线缆布线出发，通过减小环路面积的方式有效减小了其线缆辐射发射，从而排除了直流电源系统对无线电设备的干扰情况。

The airborne DC power supply system is most important power supply device for the whole aircraft and its equipment. However the DC control and voltage regulating devices itself may generate very complex electromagnetic emission, which is distributed inside the whole aircraft;among which the radio devices, especially the low frequen-cy devices like radio compass will be interfered by this electromagnetic emission. Starting from the wiring of inter-connection line between generator control box and DC generator,the cable and wire emission is reduced effectively by reducing the loop area so as to eliminate jamming case of DC power supply system on radio devices.
