Capacitors are used to store charges and capacitors alone cannot increase the voltage. Capacitors are connected along with diodes to form the voltage multiplier circuit. Capacitors can be used in many circuits where the output voltage has to be more than the input voltage.
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.
When a massive capacitor is used with a rectifier, the average output voltage is very nearly equal to the peak voltage of the supply. This implies that the actual RMS voltage of the AC supply was more than 9V. According to theoretical graphs, one should get approximately the same voltage even after adding the capacitor.
Capacitors are connected along with diodes to form the voltage multiplier circuit. Capacitors can be used in many circuits where the output voltage has to be more than the input voltage. When a capacitor is connected to the half-wave rectifier and full-wave rectifier the output DC voltage is increased.
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.
In the circuit, the capacitor supplies the load for part of the cycle. During this time, the voltage supplied to the load falls. The circuit operates in two modes: for part of the cycle, current flows from the input and the output voltage follows the input; for the other part, the capacitor supplies the load.
