This paper presents a failure analysis procedure on a power MOSFET in a three phase inverter. The analyzed power MOSFET has been obtained from a chopper leg in a three phase inverter when an anomalous failure is detected. At first, the X-ray microscope is utilized to inspect the failed device. A hint of the burn-out area in the chip is observed in the cross-section X-ray microscopy image. After that,...
This paper uses the empirical research methods, such as questionnaire, interview, to summarize the factors which influent the general technical curriculum implementation. The author applies the ISM technology for establishing the interpretation structure model which affects the implementation process of this course type, aiming at emerging the relationship between various influencing factors hierarchically...
