摘要
目前电机控制器的功率模块大部分是集成结构,无法直接测得结点温度,只能通过测试表面温升来计算出结点温度。文章提出一种可准确测试IRAM136-1061A功率模块结点温度的方法,并通过拟合温度曲线对功率模块实现温度保护。
Most of the current power moaules to control the motor were of the integrated construction and there was no way to test the node temperature directly. The only way was to test their surface temperature first, and then, to calculate their node temperature. A correct way to measure the node temperature of the IRAM 136-1061A power module was presented, thus, capable of realization of the temperature protection to the power modules through fitting the temperature curves.
