| Abstract |
This paper presents the use of a kelvin-emitter resistor as a junction temperature sensor in IGBTs. The kelvin-emitter resistor is placed directly on the IGBT die surface. The resistance is then evaluated using a sensing current injected between the power-emitter and kelvin-emitter terminals. The kelvin-emitter resistor is part of the overall gate resistance of the IGBT. Due to the resistor design, the temperature measured is a local temperature that correlates with the top of the resistor. |
