| titleOfInvention | On-line testing device and method for thermal resistance of IGBT module power cycle-vibration experiment |
| abstract | The invention provides an IGBT module power cycle-vibration experiment thermal resistance on-line test device and method, including an automotive-grade IGBT module, a power cycle circuit system, a vibration test bench, a special fixture for the IGBT module, a constant temperature water cooling system, and an IGBT gate control system. , data acquisition system, data analysis system. The special fixture for IGBT module fixes the automotive-grade IGBT module on the vibration test bench. The power cycle circuit system provides current for multiple series-connected automotive-grade IGBT modules. The vibration test bench provides different excitations for the automotive-grade IGBT modules to be tested. The control system controls the turn-on and turn-off of the automotive-grade IGBT module. The data acquisition system will collect the collector-emitter voltage of the automotive-grade IGBT module in real time. The data analysis system processes and analyzes the collected data based on the structure function method to obtain the automotive-grade IGBT module. Junction temperature and thermal resistance data in power cycling-vibration combined experiments. The invention realizes the real-time monitoring of the thermal resistance change and understands the thermal characteristics of the automotive-grade IGBT module. |
