A constant exposure method for DSC IGBT strobe is proposed. This method is based on two lookup tables (exposure and energy table). In this method, light box is used to generate exposure table and different flash time is used to generate energy table. Through exposure table and preflash result, we can get digital number ratio of preflash to main flash. This ratio and energy table can be used for...

For high-voltage applications, the series operation of devices is necessary to handle high voltage with limited voltage rating devices. In the case of self turn-off devices, however, the series operation of devices is very difficult. The main problem associated with series-connected devices is how to guarantee the voltage balance among the devices both at the static and the dynamic transient st...

Power electronics uses semiconductor technology to convert and control electrical power. Demands for efficient energy management, conversion and conservation, and the increasing take-up of electronics in transport sys...

In the application of vehicle power supply and distributed power generation, there are strict requirements for the pulse width modulation (PWM) converter regarding power density and reliability. When compared with the conventional insulated gate bipolar transistor (IGBT) module, the Reverse Conducting-Insulated Gate Bipolar Transistor (RC-IGBT) with the same package has a lower thermal resistan...

Trench gate structure represents the latest of Insulated Gate Bipolar Transistor(IGBT). Because there are great differences in model analysis coordinate system and carrier transport between trench planar structure, modeling method using will inevitably have deviation. Based on characteristics system, base region is divided into PNP PIN by considering two-dimensional effect carriers. According t...

This paper presents simulation results of the harmonics analysis of motor current signatures under different fault condition of CSI (Current Source Inverter) fed induction motor drive. In this work, simulation studies are performed for two different post fault conditions i.e. open circuiting of one of the six IGBTs(Insulated Gate Bipolar Transistor) gate, blowing off one IGBT .Under these fault...

We introduce a multidimensional peridynamic formulation for transient heat-transfer. The model does not contain spatial derivatives and uses instead an integral over a region around a material point. By construction, the formulation converges to the classical heat transfer equations in the limit of the horizon (the nonlocal region around a point) going to zero. The new model, however, is suitab...

Design of traction system is important to decide the dynamic configuration of high speed EMU. And one of the most important factors that determine the design of traction system is the thermal distribution of IGBT convertors. Thermal simulation of IGBT converter using a two-step methodology (temperature rise and thermal distribution) and its simulation results are presented in this paper [1]. Th...

The purpose of this study is an assessment of the Trench IGBT reliability at low temperature under static and dynamic operations by the aim of intensive measurements. The analysis of the Trench IGBT behaviour in these conditions is dedicated to the HEV applications. One question can be raised in case of the use of HEV in countries where during winter the temperature drops down -50°C or less: ar...
