Hi
Please help
I have an exam in less than 24 hours and really need the solution of this problem.It might not be a practical circuit but I need the solution .

Problem statement:
Supply voltage E = 100 V and the transformer turns ratio Ns/Np = 2.The inverter's switching frequency is 2 KHz and its output is a symmetrical square wave as shown.The load current is 8 A(DC) with negligible ripple.
Each thyristor has a control angle of 40 degrees.The transformer leakage inductance is represented by L=0.25 mH.
neglecting the transformer magnetizing inductance and its primary and secondary winding resistance and assuming ideal devices, calculate the average currents in the transistors and diodes(of the inverter).
________
I need the primary current waveform and in witch parts of it the transistors and diodes are on.

 

Guess you should have spent your money and time on the recommended textbook and reading it until you understood the material you needed for your class and not on beer and porn site fees huh?

There is no such examples in textbook.
I asked my instructor where to find such examples, he said: you have to simulate them or read IEEE papers

 

Well I guess you have to find those IEEE papers and start reading.

You got less than 18 hours to go so I suggest learning how to do basic document searches in your college library or whatever online resources the other people in the class are using to learn this stuff.

Either that or accept that people who waite until the last day to put an effort into learning what they need to know tend to spend their lives hauling garbage, mopping floors or doing other low mental skill labor based work.

 

This is rude.
what makes you assume that I have spent the whole semester doing nothing.
I had lectures, read two books used simulation programs and solved a 100 of questions.
so don't judge people if you don't know what they have done.

 

This is rude.

True, but what you have presented is only the question. There is no evidence that you know any of the math or any of the procedure. That condition asks us to do everything. Further, it suggests that you don't know how to do any part of the problem solving. How would a person arrive at that condition on the day before the test?

The rules here are that you must make an attempt to do your school work and we discover any mistakes. What you have asked is that we do your school work and you contribute nothing.

I mentioned that only I need to know is the waveform.
No equations needed to figure it out.
Anyway, time is over, and I already finished the exam.
