Hey, I wanted to ask what the purpose of capacitors are in a vsec. Looking online it seems to be safer for your battery’s because they smooth the ripple current. My question is where this ripple current it coming from? Are we talking about the back emf? Which I assumed would not be there since mosfet’s only allow current in one direction? Another thing I keep reading is that they are especially important when braking, when you break isn’t the polarity simply being switched and spiked? To cause an outburst of torque, again would’nt the mosfet’s stop the back emf current of this ?
I’m just trying to understand how esc’s work better. So far all I know is that they create a ac current on each terminal for the motor.
