The CFLs will tend to draw current over a wide part of the cycle.
** 100% WRONG !
The capacitor after the rectifier is small enough that the the ripple
is very large.
** Means the charging time is very short - fool.
No it doesn't. Where did you get that idea. The capacitor will start
charging when the mains voltage has passed the voltage that the
capacitor has discharged down to and continue until some time after
the peak. Try reducing the capacitor to zero and consider what
fraction of the cycle the diodes will conduct for.
The transistor circuit makes no effort to regulate
anything. The inductor feeding the lamp controls the current.
** All got nothing to do with the actual charging time of that first
electro.
Actually it does effect it in a very important way. Consider the
capacitor equal to zero and the transistors trying to regulate case
and you will see why.
You are both wrong and rude.
