一种IGBT元件运行状态监测装置
摘要：
本发明提供一种IGBT元件运行状态监测装置，所述装置包括控制单元和IGBT驱动器，所述IGBT驱动器设于驱动板卡上，控制单元通过光通讯接口与IGBT驱动器相连；控制单元以曼彻斯特编码的方式发送控制命令给IGBT驱动器，以使IGBT驱动器驱动IGBT元件开通或关断；IGBT驱动器检测IGBT元件在运行过程中的门极电压Vge、集电极‑发射极电压Vce、IGBT元件开通时间、驱动板卡电源电压、驱动板卡运行环境温度和电源温度，并将检测到的信号以曼彻斯特编码的方式发送给控制单元。本发明采用曼彻斯特编码的方式实现控制单元和IGBT驱动器之间的控制反馈信息交换，可将IGBT元件运行状态信息进行采集汇总并实时上传至控制单元，从而使控制单元实现对IGBT元件运行状态的监测。
摘要（英）：

The invention provides an operation state monitoring device of an IGBT component. The device comprises a control unit and an IGBT driver, the IGBT driver is arranged on a drive board card, and the control unit is connected with the IGBT driver via an optical communication interface; the control unit sends a control command to the IGBT driver in a Manchester encoding manner, so that the IGBT driver drives ON/OFF of the IGBT component; and the IGBT driver detects a gate voltage Vge, a collector-emitter voltage Vce, ON time of the IGBT component, a power voltage of the drive board card, an operational environment temperature of the drive board card and a power temperature in the operation process of the IGBT component, and sends detected signals to the control unit in the Manchester encoding manner. According to the monitoring device, Control and feedback information is exchanged between the control unit and the IGBT driver in the Manchester encoding manner, operation state information of the IGBT component is collected, gathered and uploaded to the control unit in real time, and thus, the control unit can monitoring the operation state of the IGBT component.
