Great, thanks a lot !

Homework Statement Two nodes in a network are connected by a line with an impedance of 0.5 + 1.2j Ω. The voltage at the sending end is 33KV and at the receiving end is 32.5 KV with a lag of 1.5° compared to the sending end.. Calculate the current in the line and the real and reactive power...

Thanks a lot for you help rude man, I'll think about this some more in light of what you've said.

Hey, no worries. For the record, there is no reverse built in diode.

Hi, thanks a lot for your reply. This question has been bothering me for some time, however I think I've made some real progress now with the help of a few more resources. The current through the L can me modeled as a triangular wave. Increasing when Q is on and decreasing when Q is off...

Apologies for not stating earlier, this is my first course on power electronics. I am a second year undergraduate student.

Homework Statement A boost SMPS has the following design properties: Input Voltage - Vi = 6.0v Maximum Output Current - Io(max) = 0.5A switching frequency - F = 100khz Inductor = 500μH Capacitor = 1000μF with ESR 25mΩ Consider the boost SMPS operating in discontinuous conduction...

Thanks a a lot for your reply, it's made it much easier to visualise what's going on :)

Homework Statement Consider an AC electricity system operating with a balance between generated power and the consumed power. Explain what happens to the frequency of a system if a large generator is suddenly disconnected. Explain the role of the governors of the remaining generators in...

Homework Statement Hello, just having a bit of trouble understanding this bit of code: typedef int Item; struct Node { Item data; Node* next; }; typedef Node* NodePtr NodePtr hdlist = NULL; Homework Equations None. The Attempt at a Solution I understand that...

Yes, that function is low only when they are all 0.

Hmm ok so for X0 I had A2' . A1' . A0' when I should have all that [A2' . A1' . A0']' So that becomes A2 + A1 + A0 ?

Homework Statement Given that the variables A[2:0] form a three bit grey code to represent numerical values: i) Write down all binary combinations for A[2:0], in ascending order of numerical value ii) A three bit grey code to decimal decoder is to be designed, where the outputs X[0:7]...

That's pretty much the same thing that's bothering me... I have written the question as it has been asked. I'm assuming they mean sign magnitude ?

Homework Statement Determine the number of bits needed to represent the range of results obtained when two N bit signed numbers are multiplied together. Homework Equations None. The Attempt at a Solution I considered the case when N = 3, i.e. a 3 bit signed number. The values...
