Abstract

The thermal behavior of semiconductor devices of voltage source inverters for a traction frequency converter and its control systems are investigated. A test bed for studying thermal processes in steady state and transient modes occurring in semiconductor modules with air forced cooling systems is described. The results of an experimental investigation for the Infineon FF300R06KE3 module are analyzed and compared to the results of a mathematical model. Transfer functions of a semiconductor module as an object of temperature control are synthesized with respect to the collector current, cooling air flow, and frequency switching. The control system of thermal behavior of a voltage source inverter with two control actions on the object of temperature control (cooling air flow and frequency switching) is developed. It is proposed to use an electric drive with an induction motor and scalar control system for the purposes of regulating the cooling air flow. The effectiveness of the proposed control system is confirmed by means of simulation in MATLAB/Simulink in transient and steady-state modes.
