Calculate Inductor square pulse: 2mH, 300V, 5us, 4A, A
A square wave voltage pulse on an inductance L for time duration t. You can calculate how does it change the inductor current. Current 1 (I1) is the initial current. Current 2 (I2) is the final current. Current 1 = 0 for current induced by a square wave pulse when the initial current is zero. I2=I1+(t*U/L)

Inductor square pulse formula says:
•Applying a 300V (three hundred volts) square wave voltage pulse to a 2mH (two millihenrys) inductor for 5us (five microseconds) will induce a current change from 4A (four amperes) to 4.75A (four point seven five amperes).•If the inductor current changes from 4A (four amperes) to 4.75A (four point seven five amperes) in 5us (five microseconds) by applying 300V (three hundred volts), its inductance is 2mH (two millihenrys).
•When a 2mH (two millihenrys) inductor changes its current from 4A (four amperes) to 4.75A (four point seven five amperes) in 5us (five microseconds), it means that the applied square wave pulse voltage was 300V (three hundred volts).
•A 2mH (two millihenrys) inductor will take 5us (five microseconds) to induce a current change from 4A (four amperes) to 4.75A (four point seven five amperes) at 300V (three hundred volts) voltage.
