I agree with your conclusion, what I was saying is that the ripple current does have to be taken into account when choosing the cap, I was thinking of RMS current differently than what you are describing.
I agree about the current limits. The negative current limit needs to be set according to...
I agree in theory, in practice I am wondering if there are other extra design considerations that need to be made. The stress on the components is not only based on RMS current, the ripple current has a lot of design considerations for example the output cap sizes etc.
When designing the...
Yes we are talking about CCM (Continuous Conduction Mode) operation, the attachment in the first post shows what I am talking about, the inductor current is negative for almost half the cycle in the no load case. I am trying to see if there are considerations that need to be made when you know...
I am looking for a good resource on the negative effects of having high ripple current with a buck converter at low load.
Most resources agree that you should design your ripple current around 20% of your maximum current. If you have a design with a huge swing between maximum and minimum...
GRE Test information
From what I have seen it depends on what program you are going into. For electrical engineering there is no subject test, so most coleges only need the general, where as physics has a subject test, so almost all schools require it (for masters).
Many coleges such as MIT have their whole course work set up where you can essentially take a class for free, if you look around hard enough you should be able to find what you are looking for.
capacitor for dc lightbulb
Remember in physics, a voltage ACROSS a cap can not change instantaniously. So when you apply your voltage the DROP across it cannot change
So when you turn on the source both terminals of the capacitor are at the high voltage.
Then as your capacitor charges your...
less than 2 connections at node in pspice
When I have had this problem I was using the wrong library file, there is a library file that has resisters and stuff, but is only used for drawing, so when you try to simulate everything is floating.
u sub
u=x^2
remember you can write it as x*exp[1/(4x^2)]
Edit: Umm, nevermind you cant integrate e^(1/u)
Added after 18 minutes:
my calculator says its impossible :P
Leakage currents
Yes, your leakage current through a transister is the same (similar) to the reverse diode current. They are caused by the same principles.
