Considering the influence of IGBT and freewheeling diode (FWD) on the fatigue failure process of the power module, and realizing online saturation voltage drop monitoring, can further study the fatigue failure process and mechanism of the power module. In this paper, the acceleration circuit which can realize bidirectional aging is used as the main circuit of the platform; according to the detection variables, control strategies, cooling system control, and system coordination requirements, the control system is designed. The drive detection system is designed, and the simulation verifies the effectiveness of the saturation voltage drop detection circuit, which realizes the accurate detection of the IGBT saturation voltage drop and the drive and protection functions of the IGBT. In theory, the accelerated aging test platform can realize power cycling of IGBTs and FWDs under different control strategies, accurately detect the saturation voltage drop of IGBTs and drive and protect IGBTs.
