Collector-emitter saturation voltage of the IGBTs in the conduction state, vCE, is considered in literature as an indicator to detect the incoming failure of the switch. Since this voltage drop is in the range of few volts, an accurate measurement structure must be adopted. This paper proposes a simple and efficient set-up to acquire switch voltage, current, and temperature. It utilizes the ordinary current and voltage sensors available on the inverter boards and, by a simple modification on the micro-controller code, the power cycling for accelerated aging is applied to the switch and the sampled data of the IGBT saturation voltage, current and temperature are sent to the PC online through SCI communication protocol. A Visual Studio code is adopted to store the data on the PC. The data can be used to train an artificial intelligent approach to detect the deviation from the monotonic behavior of the switch
