Discussion :: Power Electronics - Section 1 (Q.No.2)
In the below figure the average load current is 15 A. The rms value of transformer secondary current is
Answer: Option B
RMS secondary current = = 15/1.414 = 10.608 A.

|How can the RMS will be lower than average?|
|Pande said: (Aug 6, 2015)|
|How it can obtain?|

|Please, elaborate the solution.|
|Abhishek said: (Apr 2, 2017)|
|No, it's not correct.
As RMS value for full wave rectifier is = Imax/1.41.
And here Imax was not given, instead of it, Avg load current was given which is not same as Imax.
So, Irms is 1.11 * Iavg = 1.11* 15 = 16.65A.
Can anyone agree with me?

|But this is thyristor not diode.|
|Lopamudra said: (Sep 28, 2017)|
|Yeah, the thyristor is a controlled rectifier only. That means diode.|
|Kiran said: (Apr 20, 2020)|
|Explain the correct answer.|
|Renjith V R said: (Sep 10, 2020)|
|15 A is load current, So It will be the answer.|
