This video explains why you always want to have an optimum amount of capacitance, nothing less nothing more. In Transformer based power supplies capacitors play an inevitable role in obtaining usable DC supply. In this video, I demonstrate the easiest way of calculating the capacitance of the capacitor, required for a transformer power supply intended to be used with an Amplifier.
The Indian power grid supplies a sinusoidal AC voltage with a frequency of 50 Hz. However, many devices are operated with a DC voltage. When connecting these devices, the voltage must be rectified in advance. Most commonly, the rectifier circuit is constructed with a bridge rectifier consisting of four diodes. However, this circuit has a big disadvantage: It works only from the lower half-wave upwards and leaves a pulsating DC voltage. Experts speak of a high ripple.
A smoothing capacitor also called a filter capacitor or charging capacitor is used to “smooth” these voltages. It weakens the ripple. Although the capacitor does not produce perfect DC voltage, it reduces the fluctuations to a level that most devices can easily handle. The remaining ripple is called the ripple voltage.
For a voltage with as little residual ripple as possible, the capacitor must be the right size. However, it may not be infinitely large, as the diodes could be damaged. We want to explain how a smoothing capacitor can be dimensioned and how exactly it works. Our online filter capacitor calculator helps with dimensioning the capacity. The function of the smoothing capacitor
The capacitor for voltage smoothing is placed parallel to the load behind the rectifier circuit. Often, two smaller smoothing capacitors are used instead of one large one. Here, a capacitor is as close as possible to the rectifier circuit and the second as close as possible to the consumer. The capacitors help to fill in the gaps in the rectified voltage.
While the voltage reaches its highest values, the capacitor is charged. When it drops below a certain level, it discharges. However, due to the rectifier circuit, it cannot send the chargeback to the voltage source but discharges it via the consumer. This is why the ripple of the input voltage is slight when it reaches the consumer – the capacitor maintains the voltage.
