I have a BLDC motor and I want to store the regenerative power when it is braking. For doing so, I was thinking to use a capacitor bank between the driver and the power supply (48V DC).
Immediately after you turn on, the maximum current will be flowing, and the minimum voltage will be across the capacitor. As you wait, the current will reduce as the capacitor charges up, but the voltage will increase. As the voltage arrives at its maximum, the current will have reached minimum.
If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1, negative charge will build up on the bottom plate while positive charge builds up on the top plate. This process will continue until the voltage across the capacitor is equal to that of the voltage source.
Having a resistor in the circuit means that extra work has to be done to charge the capacitor, as there is always an energy transfer to heat when charge flows through a resistor. This graph shows that: the charging current decreases by the same proportion in equal time intervals.
Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it. The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope).
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
Current Stops Flowing: In a direct current (DC) circuit, the current flow effectively stops because the capacitor acts like an open circuit. The electric field between the plates of the capacitor is at its maximum value, corresponding to the applied voltage. No further charge movement occurs.

When the capacitor's terminals are not connected to anything, the charge cannot change, and hence the voltage will drop due to the capacitor equation V = Q/C V = Q / C.
A capacitor has an even electric field between the plates of strength E E (units: force per coulomb). So the voltage is going to be E × distance between the plates E × distance between the plates. Therefore increasing the distance increases the voltage. I see it from a vector addition perspective.
If you discharge the capacitor completely, then both plates have no charge and are neutral. The charge will remain however the energy will not be the same. There is energy stored in the electric field itself. If move the plates you will be doing work on the system. When you move the plates apart the voltage will increase.
Capacitance increases as the voltage applied is increased because they have a direct relation with each other according to the formula C = Q/V C = Q / V. Capacitance decreases as the distance between the plates is increased because capacitance is inversely proportional to distance between the plates according to a relationship C ∝ 1 d C ∝ 1 d.
The capacitors do not increase the voltage. A circuit capable of doing this with the use of diodes is also called a voltage multiplier circuit. Capacitors themselves are not able to increase the voltage. Capacitors store energy or act as DC blockers.
Power companies use capacitors to regulate the voltage on their primary distribution circuits the bank is shut down and improves the power factor of the circuit, which decreases the amps, which increases the voltage .
I think as we know E = V/d, and the field is same, so for field remains constant between the plates of the capacitor, while increasing the distance the potential also increases. In the same manner as that of distance so that the ratio of V and D is same always. It is easy!
