mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

BFL,
That sure looks like an "on/off" controller; the type later referred to as "low frequency pwm", in order to distinguish them from the newer technology, dubbed as "high frequency pwm". But it's not a shunt type on/off, this much seems true.
Specialty Concepts even makes reference to these controllers being the industry standard for over 30 years, whereas PWM made its way into wide use only 15-20 years ago.
Like I've said, there are those who still swear by the older technology, and I can't help but wonder if they were given a fair shake. I remember watching a 4 hour documentary many years back, where it was shown how Nintendo muscled their way into the game station market. And a similar thing happened with beta vs. vcr, as far as I can tell.
As far as pwm controllers doing nothing in bulk, I'm not sure I'd agree. No, they are not regulating voltage, as such, but I would think they are always monitoring, and perhaps maintaining a steady pulse width, if only to limit current?
