My first gut reaction was "British engineering, I hope there's no one from Lucas working there." <G>
But it sounds like they might be combining the wind
power into a PWM (MPPT) input and then feeding the batteries from one output. Or perhaps not quite since that might involve diode losses, their tech sheet isn't specific about their magic beyond "This feature gradually reduces the speed of the turbine to an eventual “idle” thus extending the working life of the windcharger." meaning, their charger
requires a wind
trubine that can be speed braked in order to throttle down it's output, instead of using a dump regulator
I'll give 'em points for a clever solution but if they're going to use a brake as a throttle...that's also going to mean routine stops at Meinke to get new brake pads in the windgen, isn't it? <G>
Still, at least someone out there is trying
to make it happen.
