Abstract
This paper proposes an online calibration method for the junction temperature estimation of power semiconductor devices in Electric Vehicle (EV) traction applications utilizing thermo-sensitive electrical parameters (TSEPs). It is achieved through the DC-link discharging operation mode of the traction inverter after the vehicle is parked, which is a natural and frequent activity in EV applications. Compared to conventional calibration schemes, the proposed method can be conveniently accomplished in a short term without the need for long-term data recording or complex operating states. The on-state saturation voltage of power semiconductors is used as a typical TSEP in this paper for the case study, and the proof-of-concept experiments based on a scaled-down inverter prototype verify the effectiveness, accuracy, and convenience of the proposed method.
