Re generative motor drive design

Other Parts Discussed in Thread: LM5122

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. 

Does TI have certain ICs that could help me with the matter ? 

Thanks a lot guys,

Best regards.

    Hi Amine,

    good day. 

    I think you can use a voltage feedback boost to achiev this function.  When brake the motor, the boost will automatic become to a Buck, without change the control parameter, just like below: 

    TI has many boost controlers (like LM5122) and simulation tools: Pspice for TI and WEBENCH. 

    Hope this can help you.

    Thanks!

    BR,
