Abstract
A measurement method includes determining a first relationship by measuring a reverse recovery charge of a semiconductor element at a plurality of conditions of a measurement device. The measurement device has mutually-different parasitic inductances at the plurality of conditions. The semiconductor element includes a diode component. The first relationship is between the parasitic inductance and a measured value of the reverse recovery charge. The method includes estimating a true value of the reverse recovery charge when the parasitic inductance is zero based on the first relationship.
