| titleOfInvention | Method, device and system for determining junction temperature of IGBT module |
| abstract | The present application discloses a method, device and system for determining the junction temperature of an IGBT module, and relates to the technical field of electric vehicles. The method includes: periodically acquiring a first voltage signal representing the junction temperature of the IGBT module, where the first voltage signal is a The filter circuit filters the output voltage of the temperature sensor, and the temperature sensor is a temperature sensor that collects the junction temperature of the IGBT module; the working parameters of the IGBT module and the working parameters of the motor are collected periodically, and the motor is where the IGBT module is located. The motor driven by the motor controller; according to the currently collected working parameters of the IGBT module and the working parameters of the motor, the current rolling filter coefficient is determined; according to the adjacent multiple first voltage signals and the adjacent multiple adjacent rolling filter coefficients , determine the junction temperature of the IGBT module. The solution of the present application improves the calculation accuracy of the junction temperature of the IGBT module. |
