The invention discloses an IGBT device based inductance extraction method and device. The method comprises that first current and voltage parameters in an ON moment and second current and voltage parameters in an OFF moment of a to-be-measured IGBT device are obtained; parameters the same with the first and second current parameters serve as target current parameters; a first voltage relation anda second voltage relation of closed loops in the ON and OFF moments of the IGBT device are established according to the target current parameters and corresponding voltage parameters respectively; anda difference between the first voltage relation and the second voltage relation is calculated to eliminate a resistance parameter variable and further to obtain an inductance parameter in the closedloop. The first current and voltage parameters in the ON moment and the second current and voltage parameters in the OFF moment of the to-be-measured IGBT device are collected, the resistance parameter variable in the loop is eliminated by calculation, and the inductance parameter in the closed loop can be extracted accurately.
