PWM, as implemented on a number of VV mods is a big problem for low wattage vapers. Just saying. I think it's a marketing mistake.
cozzicon,
You're one of my go-to tech-savvy "reality" sources. No hyped BS from you, which I really like.
Your post implies---and I agree---that the problem is in the
implementation of PWM, not simply the mere fact that PWM. I'm not an engineer or a tech geek, but I've learned that numerous variables influence PWM's end result---for example, filtered vs. unfiltered output. No doubt other factors come into play as well. I saw a video about PWM showing "nano-spikes" at the beginning of each micro-pulse that can be much higher than the voltage of the on-pulse itself. Could those be a factor in the Vmax (and Ovale V8) seeming to hit so much harder at low voltage settings?
If so, then that nano-spike is surely an engineering
choice---and one I personally don't approve of. I want vaping at 3.7 volts to
feel like 3.7 volts
consistently across all devices, and I'm not thrilled that I have to compensate on the Vmax and Ovale V8 because the voltage settings feel skewed toward more power.
You do know that ProVari uses PWM, right? I'm just guessing here, but perhaps PWM makes the whole business of voltage regulation easier for the software engineers to achieve, in terms of maintaining voltage in different ways: 1. during the hit, 2. over successive hits (from one hit to the next), and 3. as the battery drains to the level of providing only marginal current.
