I was working on the BlueRobotics T100/T200 thrusters with the BlueRobotics Basic ESC, to study its voltage/current characteristics curves and so hooked it up to a DSO.
I noticed that there are ripples when I switch ON and switch OFF the thrusters. And furthermore, the Ripples are huge when I turn the thrusters OFF.
I would like to know ;
- if it is related to back emf or regenerative braking?
- how to filter these ripples with any capacitor bank or other solutions?
