The CFLs will tend to draw current over a wide part of the cycle.

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.



JESUS CHRIST you are ONE ARROGANT *** !!!!!!!!

I posted ACTUAL data and YOU FUCKING SNIPPED IT !!

YOU *** - YOU FUCKING *** !!!!

Go measure the current draw waveform of a few CFLs - instead of sitting
on you FAT ARSE making up WRONG theories and misinforming people.

Have look at figure 11 for a typical current wave.

Figure 12 shows the same lamp operated from a common triac dimmer at full
setting.

The capacitor will start
charging when the mains voltage has passed the voltage that the
capacitor has discharged down to


** The charging time constant is very short for a CFL, typically about 50 uS.

Peak current is reached in 200-500uS and then drops off rapidly.

MooseFet's analysis seems evidently correct. Why would the capacitor not start charging as soon as the input voltage (minus the forward rectifier drop) reaches the capacitor's voltage? Why would it stop charging before the input voltage peaks?

Why bother with facts and standard electronics knowledge and experience?
Let idiots live in their own distorted world...
