    hi..im working in a project, voltage booster for BLDC motor.
    can anyone suggest how am i going to do it?

    A better question might be, why? What are you trying to do?

    hi.
    how do i recapture the energy of a BLDC motor during braking?
    any circuit suggestion for it? thank you

    i want to boost the voltage induced by the BLDC motor during braking for regenerative braking. i not really familiar with electronics. so any helps would help.

    Well a starting point is you would use diodes that would activate when the induced field collapses. From there you could try and boost it to higher levels but I am not sure how efficient it would be. The induced field would collapse pretty fast and you would need a switching application to produce a boost circuit (ie. switching an inductor and cap with a fet at a set frequency). Even with this I am not sure if you could apply that to the battery load to charge the battery.

    You would almost be better off using the induced field to charge a capacitor and then determine a way to use that for charging.
