Hi,
I would like to know the best way to extract dc power from a dc motor that rotates in both directions.
I'm building an human energy harvester, which uses knee joint movement to rotate a shaft, connected to a dc motor via a gear train. I want to extract power from the flex/extension phases, in which the leg moves backwards/forwards around the knee joint, and the dc motor rotates clockwise/counter clockwise. I want to use a circuit which will output the maximum amount of dc power.
I was thinking of using a bridge rectifier, but I'm not sure if this would work/ if there would be too much voltage/power loss across the diodes. Are there any better circuits to use?
thanks!
