Thoughts on a switching dummy load, for a DC-converter, which redirects power back to the input.
At a minimum load of 0.6A, we're talking 20.4W just to power the thing with no useful load attached!
These are floating-output converters with a wide input voltage range, which, I'm pretty sure, means, if done right, the outputs can actually be placed in series with the input.
No, we're not talking free-energy, here... we're talking recovery of otherwise burnt energy.
Though, I've also pondered this same output-in-series-with-input to maintain the minimum input voltage while, say, half the series batteries are removed from the circuit for charging.
Oh, and this dummy-load would also decrease as the actual load increases.
And then *really* vague thoughts on using a similar technique, and the scaling necessary, to replace resistors in many general cases. Please send me some moolah and some credit if you steal this idea!
