Abstract:
A method of estimating a junction temperature of a converter for a vehicle includes: calculating, by a vehicle controller, an IGBT power loss value of the converter using an input current and an input voltage between a battery and the converter, an output voltage output from the converter to an inverter, and a duty ratio and an IGBT characteristic value of the converter.
