The invention relates to a motor controller active short circuit control method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: under the condition that an external fault exists in a motor active short-circuit control system, obtaining the switching tube temperature of a six-path IGBT (Insulated Gate Bipolar Translator) switching tube; when the temperature of the switch tube is not greater than the temperature threshold, detecting whether low-voltage power supply of the motor active short-circuit control system is normal or not; and under the condition that low-voltage power supply is normal, an active short circuit instruction is sent to the driving unit through the microcontroller so as to indicate the driving unit to execute short circuit on the six IGBT switching tubes. By adopting the method, temperature detection and power failure detection can be carried out in the active short circuit control process, the problem of device performance failure caused by overhigh temperature of a power switch tube in the active short circuit process and the problem that active short circuit entering cannot be judged due to power failure of a low-voltage power supply are avoided, and the safety and reliability are improved.
本申请涉及一种电机控制器主动短路控制方法、装置、计算机设备、计算机可读存储介质和计算机程序产品。所述方法包括:在电机主动短路控制系统存在外部故障的情况下,获取六路IGBT开关管的开关管温度;在开关管温度不大于温度阈值的情况下,检测电机主动短路控制系统的低压供电是否正常;在低压供电正常的情况下,通过微控制器向驱动单元发送主动短路指令,以指示驱动单元对六路IGBT开关管执行短路。采用本方法能够在主动短路控制过程中进行温度检测和掉电检测,避免了在主动短路过程中功率开关管温度过高引起的器件性能失效问题和低压电源掉电引起的无法判断进入主动短路的问题,提高了安全可靠性。
