Regenerative motor drive

Hi guys,

I have a motor that runs with 24V. My input battery gives me 12V. I need to control this motor with either a DCDC or any type of boost circuit.

However I also want this drive to be regenerative. In certain circumstances my motor will start spinning faster because of the environment so I want to use this energy to recharge the battery.

Do you guys have any circuit topologies to recommend ? This is my first time designing such a circuit.

Thanks a lot guys,

Best regards.

In the process of Boosting the Voltage, You will loose ~20 to~30% of your available Power,
so any "regenerative" process is totally a moot-point.

Every time Energy is "transformed", from one form to another form,
Energy will be permanently lost in the form of Heat-Generation.
