本发明公开一种车用发电机励磁模块，包括一框架和至少一个焊接在框架上的半导体单元，半导体单元包括至少一芯片和至少一跳线，芯片的一极焊接在框架上，另一极焊接有跳线，跳线的末端焊接在框架上，本发明解决了现有技术中存在的芯片尺寸受限、散热差、制作效率低的技术问题。
Description
本发明涉及车用发电机励磁系统技术领域，特别涉及一种车用发电机励磁模块。
发电机励磁系统是供给同步发电机励磁电流的电源及其附属设备的统称，励磁系统是发电机的重要组成部份，它对电力系统及发电机本身的安全稳定运行有很大的影响，励磁系统的主要作用有：1)根据发电机负荷的变化相应的调节励磁电流，以维持机端电压为给定值；2)控制并列运行各发电机间无功功率分配；3)提高发电机并列运行的静态稳定性；4)提高发电机并列运行的暂态稳定性；5)在发电机内部出现故障时，进行灭磁，以减小故障损失程度；6)根据运行要求对发电机实行最大励磁限制及最小励磁限制。
如图1所示，励磁二极管是励磁电路中用来整流的常用原件，车载发电机的励磁电路中的励磁二极管，常常做成多个二极管焊接于同一个框架的结构，并对框架上二极管区域进行塑封制得励磁模块，从而便于安装且提高了整流二极管工作时的工作效率，但是该种结构的励磁模块存在如下缺点：
1、由于励磁模块受到安装空间的限制，其体积需要保持在一定的范围内，故整流二极管需要横置并焊接于框架，从而使得励磁模块满足尺寸要求，但是二极管横置，此时二极管内部的芯片处于垂直框架表面的位置，其内部芯片尺寸往往被限制的较小，从而限制了励磁模块的性能；
2、由于二极管体积受限，导致其内部芯片体积受限，芯片散热面积较小，散热性能不佳，使得励磁模块的可靠性降低、失效率增加；
3、整流二极管在焊接于框架前，需要先将整流二极管两端引脚剪断，再人工将引脚焊接于框架，由于整理二极管引脚有两个，而一个框架需要焊接数个整流二极管，从而导致该种励磁模块制作工序繁琐、制作效率低下、 制作成本较高。
