The invention discloses a driving power assembly and an electric driving system. Wherein the power assembly comprises a driving circuit board, a laminated busbar and a cooling water channel which are sequentially laminated from top to bottom; a power board is fixed on the side surface of the cooling water channel, a plurality of mounting areas which are linearly arranged at intervals along the horizontal direction are arranged on the power board, the mounting areas are used for mounting IGBT power units, so that the IGBT power units are vertically arranged, and pins of the IGBT power units can penetrate through the laminated busbar to be welded and fixed with the driving circuit board. According to the driving power assembly, modularized arrangement of the IGBT power units can be achieved, different numbers of IGBT power units can be arranged according to different power requirements, the overall layout structure does not need to be modified, the operation stability of the driving power assembly is guaranteed, the design efficiency is greatly improved, and the research and development risk and the research and development cost are reduced.
本发明公开了一种驱动功率组件和电驱动系统。其中,功率组件包括由上至下依次层叠设置的驱动电路板、层叠母排和冷却水道;冷却水道的侧面固定有功率板,功率板上设有多个沿水平方向一字排列且间隔设置的安装区位,安装区位用于安装IGBT功率单元,使IGBT功率单元呈立式设置,IGBT功率单元的引脚能够穿过层叠母排与驱动电路板焊接固定。该驱动功率组件能够实现IGBT功率单元模块化设置,可以根据不同的功率需求设置不同数量的IGBT功率单元,无需修改整体的布局架构,保证了驱动功率组件运行的稳定性,大大提高了设计效率,减少了研发风险和研发成本。
