چکیده
The effectiveness and reliability of the unified power flow controller (UPFC) are determined by insulated gate bipolar transistor (IGBT) valve. Thermal losses, conduction switching losses in IGBT valve all affect efficiency UPFC. failure rate converter valves is influenced junction temperature, which has an impact on converter's reliability. Piecewise linear electrical circuit simulation (PLECS) was used to simulate two valve-based legs working at 12000 Hz, part number GT30F123. By reference characteristics produced PLECS, thermal analyzed. Simulation results corroborated with analytical measurements. chance achieving 100%, 50%, 0% functioning modes among indices that a hundred percent, fifty or zero percent mode assessed. frequency state probability mean time failures (MTTF) obtained from probabilities using Markov model. rate, lifetime UPFC quantified give complete picture UPFC's performance.

Simulators in power electronics are less developed than in other electronic fields. The main modelling methods are between the numerical simulation of semiconductor device equations that hardly simulate circuits, and equivalent circuit models that show poor accuracy. We propose the application of the bond graph techniques to model modular power semiconductor devices. Furthermore, the IGBT is a ...

A new insulated gate bipolar transistor structure, the 3D-IGBT, is presented. The 3D-IGBT utilizes selective epitaxial silicon to form a top contacted anode and still retain the cellular structure of vemcally oriented devices. The 3D-IGBT , unlike other fully integrable power devices, exploits the merits of cellular structure to increase its packing density and thus reduce its on-resistance per...
