How the three phase rectification is achieved?
You achieve three phase rectification with a three phase rectifier. There is one in the alternator of you car. You have three windings, connected delta, so there are three terminals. Three diodes are connected to these terminals, anodes towards the terminals, cathodes common and connected to the battery. Three more diodes (for a total of six) are connected to the terminals, cathodes towards the terminals, with the anodes common and connected to ground. At any one moment of time, one winding provides voltage to cause two diodes to conduct, charging the battery. As the alternator rotates, the windings and the diodes take turns, effectively providing a three phase AC to DC power source to the battery. If you look closely, there is another set of three, smaller, diodes connected as well, anodes towards the terminals. These diodes provide power for the integrated regulator, but the six main diodes are large and heatsinked into the frame of the alternator.
What is back to back diode?
A: Refers two two diodes connected as it say back to back for gates applications.
What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
Is superposition theorem applicable for diodes?
No, diodes are not linear elements like resistors are. Current can only flow in one direction in diodes.
What is DC reactor in inverter?
This is used to improve the input power factor of the inverter power supply and reduce harmonics. The ''DC reactor'' is more effective than the input reactor in improving the power factorDC reactors (link chokes) are connected after the input diodes in the power circuit. One of the disadvantage of the DC reactors is they are located after the input diodes, and do not protect the diodes from possible voltage transients. One coil is needed in a DC circuit versus 3 coils in the AC circuit. Additionally DC reactors smoothing the current flow limits the high peak current pulses from abusing the capacitor bank inside the converter.
Why not gate is not possible using diodes?
Diodes cannot invert, a required part of the not operation.
The metal lead of p type of one pn diode connected to the metal lead of p type of another pn diode makes a npn transistor?
No. You cannot create a transistor by connecting two diodes together. There is an interaction between the junctions of a transistor, said interaction being not possible when two diodes are connected together.
Why is the direction of diodes in alternator diode trio is opposite to the direction of diodes in the rectifier bridge?
A three phase alternator will have six diodes in the rectifier bridge, three with their anodes connected to the phases, and cathodes commoned to the positive terminal, and three with the cathodes connected to the phases, and anodes commoned to the negative terminal, which is likely the housing of the alternator. The trio diodes arrangement will match the positive rectifiers, i.e. anodes to the phase connections, cathodes (denoted usually by a stripe around the body on small diodes), connected to the D+ terminal

Is it possible to design a transistor by using two diodes practically?
No.
Can you do amplification without transistor and is it possible to design oscillator using diode?
Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.
When the output of two 5.6 volts zener diodes circuits are connected in series do you obtain 2x5.611.2 volts?
If you are saying that the Zeners are connected in series, the answer is Yes.
How many diodes can be used in center tap type rectifiers?
There are two diodes in a standard center tapped configuration of a rectifier. This is per phase, so if you had a three phase system, each winding having a center tap, all of which are connected together, you would have six diodes.
How many diode makes one transistor?
When investigated with an ohm-meter, a transistor resembles two diodes connected "back-to-back". But you can't make a transistor by connecting two diodes back-to-back.
What is back to back diode?
A: Refers two two diodes connected as it say back to back for gates applications.
Working of bridge rectifier?
A: Very simple really 4 diodes total. the AC source assume is positive then the way the diodes are connected only one will pass current which in turn pass through the load and pass trough a diode has an anode connected to it and exit to the negative AC source. And repeat for negative.
If one of the diodes in the rectifier is opens what should be possible output voltage?
low output
