Novel Techniques to Reduce Transformer Inrush Current Using EMTP Software
Transformer inrush current is a high-amplitude, non-sinusoidal transient that occurs during initial energization, leading to voltage dips, power quality degradation, and relay misoperations.

Transformer differential protection with wavelet transform and difference function
The Transformer Differential Protection (TDP) algorithm instantly compares the target transformer’s terminal currents for each phase. The differential current is not expected to appear during regular operation.

Elimination of current spikes in buck power converters [PDF]
Current spikes in a buck power converter due to commutating diode turn-off time are eliminated by using a tapped inductor in the converter with the tap connected to the switching transistor. The commutating diode is not in the usual place, but is instead

Rectification Free from Inrush Current
A simple stopper of inrush current, with TRIAC, is proposed for rectification systems. Among all the switching devices only TRIAC has reverse trigger-mode that enables direct triggering by the voltage of capacitor, only after its charging up through a resistor.
