  • SENSING JUNCTION TEMPERATURE OF POWER TRANSISTORS
    Publication number: 20220018720
    Abstract: A method for estimating a junction temperature of a power transistor used in an inverter, comprising measuring a temperature-dependent characteristic of a power semiconductor comprising the power transistor used in a power semiconductor module adapted for use in the inverter, and estimating the junction temperature of the power semiconductor using the mathematical relationship between junction temperature and the temperature-dependent characteristic of the power semiconductor. Measurement of the temperature-dependent characteristic and estimation of the junction temperature therefrom is free from using a discrete sensing element.
