In a Full Wave Rectifier two diodes act to rectify both positive and negative cycles. A transformer is generally used to isolate the 120VAC (20A) from the secondary. 1. On the positive halfcycle C1,C2,C,C4 charge to +Us thru D2 and D4. D1 and D3 are blocking. 2. On the negative halfcycle C1,C3, charge to -Us, but C2 and C4 can not discharge.

A diode is an electronic component with two electrodes which a signal can flow between (but thermionic diodes can have one or two more electrodes). The most common function of a diode is to allow an electric current to flow in one
A diode is a semiconductor device, made from a small piece of semiconductor material, such as silicon, in which half is doped as a p region and half is doped as an n region with a pn junction and depletion region in between.
Chapter-1: Semiconductor Diodes. Semiconductor is a chemical Element in which the conductivity lies between conductor and insulator, Hence the movement of electrons (Current Conduction) can be controlled easily by means of an external voltage (Biasing). N-Type Extrinsic Semiconductor (Doping Pentavalent element).
Basic applications of the diode will be introduced, with circuits such as the rectifier, and the limiter. Lastly, with the use of so-called breakdown diodes, we can design circuits that act as voltage regulators – i.e. circuits that provide a steady output voltage when subjected to a wide range of input voltages and output load currents.
diodes are used for voltage stabilisation, preventing unwanted variations in DC supplies within a circuit, and to supply accurate reference voltages for many circuits. Diodes can also be used to prevent disastrous damage to battery powered equipment …
