Hello,
i am member of a team and we are working on a regenerative braking project using super capacitors. We use the drv8301 kit to control our BLDC motor. Our tests were successfully completed by using LiPo batteries, but when we tried to power the kit with super capacitors, we figured out that the motor could not raises over 400 revs. The capacitors were charged on 12-13 Volts and we thought that it was the problem, because in another post Mr. Chris Clearman said that "Are you using 14.8V for the bus? I know the DRV8301 kit doesn't like a bus voltage that low unless you supply the 5V separately to J2" . But we tried to power the kit with one LiPo battery charged on same Volts and everything was ok. So what is the problem of our system? Will the problem get solved if we supply 5V separately to J2?
Thank you in advance,
John
