Abstract
A parameter determining apparatus for estimating temperature of a switching element of an inverter is disclosed. The parameter determining apparatus of the present disclosure includes an inverter unit including a power semiconductor module configured with at least one or more switching elements, and a control unit configured to determine an initial collector-emitter voltage of each of the switching elements and collector-emitter resistance of each thereof by linearizing a collector-emitter voltage of each of the switching elements at a certain temperature.
