Using PWM to regulate power dissipation

[dorke]

To be honest, i don't really know how to watch it in the frequency domain. Can i do this with an ossiloscope? Or should i use the program that you suggested in the other post? About the generator, i can't acces it right now so i can't give anymore information about it. Next week i'll return to ESAT (the lab where i perform the tests and then i can investigate it. Thanks anyway for the help so far! I'll keep you up to date next week

Some scops can do an FFT on the signal,
but not the one you are using (Tek 2430A).

Yes,use the software in the thread.
Hooking up to a PC audio card can be done with the Tek scop output signal(on the rear panel).
How are you actually measuring the current,a current probe?


To answer the question about the village consumption.
It depends very much on the ratio of their consumption to the Generator power capability .
And the type of lighting they may use LED/CFL

Every time you convert AC to DC using diodes aren't you are adding a non linear load into the mix?

Yes,
but the op now refers to #16 in which he only has an L-C in it.

I am getting confused now, this is jumping about too much for me.

I guess i am, but the thing is that i had the same problem when i only connected the capacitors (see post 16 in this thread)

Why do you have the 100uF cap on the input to the bridge?

I need them to level everything out otherwise i draw a current like this:

When you do check that generator again do this:
Disconnect all loads to it (capacitor included).
Measure it with no load .
Then use a pure ohmic load and measure again.

Find out what is the power capability of the generator.
Find out if it has any voltage stabilization circuits and what they are.
