According to the theoretical graph, I should get approximately the same voltage even after adding the capacitor. However, the voltage varies depending on the capacitance of the capacitor, approximately from 12-16V. There might be an equation to determine the actual output voltage based on the capacitor's capacitance. It would be great to get 12V out of the system.
When a capacitor is delivering power to a load, the voltage supplied to the load initially falls. However, as the next peak of the AC waveform arrives, the rectified input voltage reaches and exceeds the output voltage, causing the output voltage to follow the input voltage again.
However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective Series Resistance (ESR). In the scenario above, you will double the ESR. High ESR can cause unwanted or catastrophic effects on circuits not designed to handle it.
Load division increases the power transfer capability of the system and reduced losses. Control of Voltage – In series capacitor, there is an automatic change in Var (reactive power) with the change in load current. Thus the drops in voltage levels due to sudden load variations are corrected instantly.
They may cause overvoltage or resonance problems if not properly designed or protected. For example, during a fault condition, the voltage across the capacitor may rise up to 15 times its rated value, which can damage the capacitor or other equipment in the system.
in a capacitor cannot exceed 110% of its rated voltage.— If the number of faulty elements in a unit is so high that there is a danger of provoking a chain reaction of faults, the battery must be disconnected even if the voltage has not exceeded 110%

Voltage control can be properly maintained by the gener-ation or consumption of reactive power. Generation of reactive power will increase the system voltage while consumption of reactive power will decrease the system voltage.

How Distribution Capacitor Banks Compensate for Inductive Loads
Examining the IL and IC currents in this graph, we can see that they''re 180° out of phase with each other. This makes sense because IL lags the source voltage by 90° and IC leads the source voltage by 90°, so they''re 180° from each other. From the source''s perspective, that means that they cancel each other but what it really means to ...
