Film capacitor assembly and motor controller

The invention provides a thin film capacitor assembly and a motor controller, and belongs to the technical field of motors. The thin film capacitor assembly comprises a plurality of cooling pipes, a plurality of columns of silicon carbide single pipes and a plurality of columns of capacitor cores. The multiple cooling pipes are arranged in parallel, a cooling channel is formed between every two adjacent cooling pipes, and cooling liquid is contained in the cooling pipes. Each row of silicon carbide single tubes are located in one cooling channel, each row of capacitor cores are located in one cooling channel, and the silicon carbide single tubes and the capacitor cores are located in different cooling channels. Therefore, the heat dissipation effect in the thin film capacitor assembly is good, the temperature of the thin film capacitor assembly is prevented from being too high, and the temperature resistance degree of the thin film capacitor assembly is further improved. 本公开提供了一种薄膜电容器组件和电机控制器，属于电机技术领域。薄膜电容器组件
