In order to calculate hundreds of phase slot leakage inductances of a 12/3-phase dual stator-winding induction generator,new analysis methods are utilized to acquire slot leakage permeances and determine relationships between windings and coil sides.

1D models of windings AC resistance and leakage inductance in high-frequency transformer;

Isolated full bridge boost converter is attractive in single-stage Power Factor correction(PFC) with isolation requirement,but the major disadvantage is that the transformer leakage inductance causes high transient voltage across the bridge switches,which increases the switching rating and decreases the reliability.

The leakage inductance of power transformer is one ofthe main interference sources in the circuit.

The condensing performance of 6 spiral baffle condensers of flat roof and different spiral angles and with or without uncorked slots are tested on a test bench.

Winding design and calculation on rotor slot leakage reactance of a 3Y/3Y pole-changing motor;

The slot leakage reactance,end region leakage reactance and armature reaction reactance of Powerformer are calculated with FEM and compared with the results calculated by traditional electrical machine design method.

As to the deformed slots,the slot leakage reactance has been analyzed in theory and therefore formulized.
