That was intentional, I wanted to have a negative output voltage, that is why they are reversed :) Here is what the output is supposed to look like in this configuration using another program http://img703.imageshack.us/img703/355/cmgy.png

Hello :) I have created a flyback converter model using Simpowersystems in Simulink/Matlab. But it always gives me the wrong answer! I have simulated the same system using PLECS and Simscape/simulink and got the correct answer. But with my Simpowersystems model, it always gives me the wrong...

Hi, Can you post the original PDE with the initial conditions.

You can't escape mathematics! Or physics! Engineering is applied math! I am an engineering student, and almost all the courses I took included math one way or another. I think so! Fuel cells, bio-fuels, combustion all involve chemistry ;D

Thanks, you have confirmed what I have suspected :D, I have literally spent hours trying to figure out who's wrong, me or the book.

Nodal analysis not mesh analysis :), Anyone?

EDIT I mean nodal, not mesh analysis xD http://img205.imageshack.us/img205/5931/omgt.jpg http://img694.imageshack.us/img694/2570/omg2p.jpg Are my are my equations correct? Here is the solution according to wolfram...

You're right it is a function of (t) xD! Silly me. I've just checked. So is he right after all?

Well, that's what I have written in my notes, what's wrong? Omega is the angular frequency Though he never substitutes it. So, should I go have a talk with him? But the questions are multiple choice, so if I use a different form I'd get a different answer :(

My math professor doesn't include the correcting (normalizing factor) neither in the Fourier transform nor in the inverse Fourier! He says that it's optional. It is weird because I have seen it used in all the textbooks! Is it a big deal? He defines the Fourier transform as:-...

Hmm I am going to take Analog electronics and Circuits 2! Both with their labs :) I might also take Instruments and Measurements with its lab :(, and Engineering Economics. Fluid Mechanics plus AutoCad or Digital systems. And of course Partial Differential Equations! This is going to be a...
