How do we calculate the rise in DC bus voltage during negative torque conditions on a PMSM Motor

I have two PMSM motors connected back to back with a coupled shaft. Both the motors have independent motor drive inverters driving them. One motor (Motor A) is operating in speed mode, meaning its job ...

Use capacitor to store energy during regenerative braking

I have a BLDC motor and I want to store the regenerative power when it is braking. For doing so, I was thinking to use a capacitor bank between the driver and the power supply (48V DC). The peak ...

Do computer/datacenter power supplies utilize regeneration (like in motor control)?

In a PC power supply I have, it implements a synchronous buck converter that uses two active switches without a diode. I found a picture of the schematic online, whose link is below: https://e2e.ti....

Adjustable regenerative braking

In electric cars, one way to brake is to turn the motor into a generator, extracting energy from the motor, and slowing the car down. I'm not sure, but my guess for how to decrease and increase the ...

At what relative speed (slow/medium/ or fast) do electric skateboards recharge the most efficiently while going downhill? [closed]

Most electric skateboards recharge while going downhill. What would be the most efficient relative speed to go down hill? I would argue that going slower would use less energy and recharge the battery ...

How is amount of regenerative braking in DC motor controlled

I know that if you spin a DC motor by an external force, it can create electricity, hence it can be used to charge a battery or something. This is used in regenerative braking. But how can be the ...
