This paper proposes the experimental characterization and modeling of thermal runaway phenomena affecting high-voltage devices in the blocking state. In particular, it considers 6.5 kV rated multi-chip IGBT modules, of the kind employed in railway traction applications, showing how temperature and reverse bias voltage influence the off-state power losses and how the same thermal design may yield thermal...
This paper proposes the complete closed-loop model development of a railway traction drive, also taking into account the coupling between electrical and thermal effects. The work is based on VHDL-AMS and consists of four sections: the first deals with the compact model development of the asynchronous motor and its corresponding control sequence; the second is devoted to the DC/AC converter with PWM...
