And, it is also possible to the final candidate value of computing repeatedly in (11) formula or (12) formula, until final candidate value L_hat
(k+1) till the time being less than threshold value Δ L_th with the difference of setting value L_hat (k) exceedes the time set in advance.In the case of being somebody's turn to do,
Identification pattern can be terminated in the stable time point of final candidate value L_hat (k+1).
And, the value of q shaft current Iqe can also be more than the beginning bar of the situation of value set in advance as identification pattern
Part.In the case of being somebody's turn to do, can more accurately identify the inductance of reactor 8.
And, it is also possible to the computing repeatedly in final candidate value L_hat (k+1) terminates it in a period of identification pattern
Before, do not update setting value L_hat (k).In the case of being somebody's turn to do, can suppress whenever computing final candidate value L_hat (k+1) repeatedly
Whole candidate value L_hat (k+1) changes.As a result, power factor during identification pattern can be suppressed to change.
And it is possible at least one party in switch element 9a and flywheel element 9b is formed by wide band gap semiconducter.Broadband
The proof voltage of gap semiconductor is higher.The allowable current density of wide band gap semiconducter is higher.Therefore, it is possible to reduce switch element 9a
With at least one party in flywheel element 9b.As a result, the regeneration with switch element 9a and flywheel element 9b can also be reduced
Converter apparatus 3.
