Abstract:Inverter is one of the main components of a power system, and SVPWM algorithm is the key part. The principle and algorithm of SVPWM are introduced. The scheme can easily determine the location of the reference vector and calculate the on-times. It uses the corresponding switching sequence to generate gating signals for the inverter. On this basis, the simulation model with the Matlab / simulink as platform was established. Simulation results is consistent with the theoretical analysis. | |||

Abstract:With the knowledge of heterogeneous characteristics of thermal barrier coating materials at mesoscopic level, a coupled thermo-mechanical-damage (TMD Model) model was introduced and used to numerically quantify the thermal stresses and crack development of in thermal barrier coatings (TBCs) composite subjected to decreased temperatures. The effect of different surface precrack morphologies, such as precrack length and precrack density, on an interface crack subjected to thermal loading caused by a temperature change is presented. It provides us with a more sensible physical intuition and a more accurate mathematical for optimizing the design and the processing of ceramic coatings subjected to the coupled thermal-mechanical loading | |||
