To determine the required capacitance for a 6 volt 100 amp rectifier, you would need to know the ripple voltage that the circuit would tolerate. You would also need to know the ripple frequency. More specifically, you would need to know the time from one peak value to the intersection of the capacitor's voltage decay curve and the next turn on point for the rectifier.
Let's say that the tolerated ripple voltage is 1 volt, and that the ripple frequency is 120 hertz, as provided by a full wave rectifier. This is a period of 8.3 millseconds. The actual time from ripple peak to ripple trough is actually slightly less than 8.3 millseconds, but that is a function of ripple slope, as somewhat complex calculation, so lets use 8.3 millseconds, which will be conservative.
1 volt in 8.3 millseconds is 120 volts per second. Plug that in to the equation for a capacitor ...
dv/dt = i/c
..., along with the current of 100 ampere, solve for c and you get ...
dv/dt = i/c
120 = 100/c
c = 100/120
c = 0.83 farads
Now, 8.3 farads is a very large capacitor. Lets improve the situation with a three phase rectifier. In that case, the ripple frequency is 360 hertz, or 2.8 milliseconds, requiring a 0.28 farad capacitor, still a large value, but better than 0.83 farads.

How many constraints should be taken in optimal placement of capacitor problem for voltage improvement using Particle swarm optimization?
Four constraints should be taken in optimal placement of capacitor problem for voltage improvement using the Particle Swarm Optimization.
How many diodes are used to make a half wave rectifier?
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
What is the ripple factor of full wave rectifier?
although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application. the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters

How is ac convert into DC?
Think of AC as a wave that undulates between a peak positive and negative value. Now if you flip the negative half of the wave above zero line you have all the peaks positive. This is done with what is called a full wave rectifier. Now you need to smooth out the humps into a steady single voltage which is DC. This is done by a circuit with a capacitor as a key component. The capacitor and some other components smooth out the "ripples" to produce the desired DC voltage.ams to voltageA bridge rectifier is usually used in this application. Most portable electronic devices utilize d.c. power. Yet, in order to recharge depleted batteries, they are plugged into an a.c. outlet. In many cases, the cord connector housing that plugs into the outlet has a bridge rectifier built into it that converts a.c. to d.c. voltage.

Types of rectifier?
There are basically two types of rectifiers one is the half wave rectifier and the other is the full wave rectifies. The full wave rectifier is further classified into two types namely the bridge rectifier and the center tapped rectifier.There are also silicon controlled rectifiers nowadays.

How many diodes does a center -tap type rectifier use?
Two
What does a disc capacitor do?
A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.
