Hello everybody,
I'm following the EEVBlog from few months and I think its time for me to be active on the forum.)
I'm working on a streering wheel with force feedback (hobbystic project) and I need to protect the power supply from regenerative current from the DC motor.
If I'm not wrong, I need a shunt regulator to waste the extra energy from the motor, but I need to order it. So, in the meantime, I'm wondering if I can do something with the part I'm already using.
I'm using an AC adapter at 24V to power up the motor, a L298N, freewheeling diode and bypass caps.
The caps (2 x 100uF, 2 x 100nF) can handle some energy from the motor, but I won't rely on them, so I came up with the circuit I attached.
Can it do the trick? Am I missing something?
Thanks for the help!
Best Regards
PS: sorry for my bad English
