Thanks for the suggestions. My goal is maximum efficiency, and I’m trying to take advantage of the middle of the big battery to get it.
Seems to me a simple DPDT relay would be essentially 100% efficient. Buck converters (inductive or capacitive) are usually only 90% efficient.
I’d also like...
Duty cycle to rpm is certainly an interesting metric.
I suppose the half bridge would reach a new lower rpm faster because of the braking action. FWIW.
However, you cannot simply feed the PWM signal to the SD input and expect the circuit to only pulse the high side switch. The boost circuit...
I have a large 48V battery bank connected to a solar array, but I have several loads (~10A) that require 24V (currently on a small battery bank powered by a SMPS). I'd like to connect the two batteries by tapping off half of the 48V battery bank. Of course that would result in cell imbalance...
I'm not sure why you would use a half-bridge driver to run a uni-directional DC motor. When the low-side switch is on it will actually slow down the motor (acting as a brake and wasting energy). I think you would be better off using a VOM1271 and a single mosfet. It would be simpler and more...
