Question
A diode circuit feeds an ideal inductor as shown in the figure. Given V, where rad/s, and mH. The initial value of inductor current is zero. Switch S is closed at ms. The peak value of inductor current (in A) in the first cycle is
________.
________.
Correct answer
16.6 to 17.4
Solution
The voltage across the inductor is given by . When the switch S is closed and the diode is forward-biased, the source voltage appears across the inductor: .The inductor current is found by integrating the voltage:Given and the switch closes at ms:The peak current occurs when (which happens at ):Given values:
Calculating the reactance :Calculating :The peak value of the inductor current in the first cycle is approximately A.
Calculating the reactance :Calculating :The peak value of the inductor current in the first cycle is approximately A.
