Part.In this case, the inductance of reactor 8 can be identified more accurately.
Also, in a period of identification mode, it can also be terminated in the operation repeatedly of final candidate value L_hat (k+1)
Before, do not update setting value L_hat (k).In this case, being able to suppress whenever final candidate value L_hat (k+1) of operation repeatedly most
Whole candidate value L_hat (k+1) changes.As a result, power factor when being able to suppress identification mode changes.
