IGBT power modules are widely employed in electric vehicle motor drive applications. The thermal behavior of these modules becomes more crucial for designing the cooling system for reliable operation. This paper proposes an RC thermal model of SEMIKRON IGBT-based half-bridge inverter module for analyzing the electrothermal behavior under various operating conditions. The proposed thermal model considers the mutual thermal coupling between the devices and the self-heating phenomena of individual devices inside the power module. The power dissipation and junction thermal effects are investigated with and without power module chip mutual couplings. The electrothermal model is developed using the PLECS software environment and validated the same using a two-level voltage source inverter fed 34 kW PMSM motor EV application. The IGBT power loss and junction temperature profiles are presented for an electric vehicle driving cycle of European (NEDC) regulations.
