ABSTRACTIn this paper, the variation in device parameters is investigated with respect to temperature by considering the combination of HfO2-SiO2 on 4H-SiC n-IGBT. Two-dimensional numerical simulations using Setaurus TCAD have been performed to analyze the changes in static and dynamic characteristics. The switching waveforms have been analyzed using a clamped inductive circuit with and without HfO2. It seems that the presence of HfO2 in the dielectric stack has a considerable impact on the device turn off time.

The head frame is a key component which plays a supportive and accommodative role in the spindle system of CNC machine tool. Improving the static and dynamic characteristics has profound significance to the development of machine tool and product performance. The simplified finite element modal is established with ANSYS to carry out the static and modal analysis. The results showed that the maximum deformation of the head frame was 0.0066mm, the maximum stress was 3.94Mpa, the deformation of most region was no more than 0.0007mm, which all verified that the head frame had a good stiffness and deforming resistance; several improvement measures for dynamic performance were also proposed by analyzing the mode shapes, and the 1st order natural frequency increased 7.33% while the head frame mass only increased 1.58% applying the optimal measure, which improved the dynamic characteristics of the head frame effectively.
