METHOD AND SYSTEM FOR AUTOMATIC DETERMINATION OF INDUCTANCE |
摘要 |
A method and system for determining an inductance value of an inductive element are presented. The method includes energizing the inductive element using an N-pulse AC to DC converter in electrical communication with the inductive element and an AC source. The method further includes determining at each of a plurality of periodic time intervals an inductive element voltage value, an inductive element current value, and an equivalent source phase angle. An Nth harmonic impedance squared value is then determined for the inductive element using the inductive element voltage and current values and the equivalent source phase angles. The inductive element inductance value is then calculated using the Nth harmonic impedance squared value and an AC source frequency value.
