Capacitors in dc circuits |
Well, that link does indeed say that, "Capacitors do not play an important role in dc circuits". If you read the next line you will see a very important bit of math: "the current stops flowing as soon as the charge
on the positive plate reaches the value
". This is how a capacitor helps stabilize the output from the bridge rectifier. When the bridge output voltage is higher than the voltage on the capacitor, charge (current) flows in. When the bridge output voltage is lower than the voltage on the cap, charge flows out, this charge storage and release has a stabilizing effect on the output voltage and results in a waveform like the one posted by jlauteam1.
I am also having real trouble figuring out what possible use a 1:1 transformer would be in this situation.
