Semi-conductor diodes used in electronics engineering in general is used to rectify the AC current into DC.Dioda formed by atoms of P and N atoms are combined into one, which will form the arrangement as shown below.<\/span> Semiconductor diode arrangement and Symbols<\/span> The diodes can be used to rectify the AC current into direct current rectifier diodes DC.Ada are two kinds of half-wave rectifier and full-wave rectifier.<\/span> In Figure below shows the half-wave rectifier circuit.<\/span> When the switch S is closed in the secondary windings will be induced alternating voltage.<\/span> At the time t1 to t2 A moderate positive voltage so that the end of the half period of this diode will pass current I. This current will pass RL prisoners, so that between the ends C and D occur voltage proportional to the magnitude of the current.<\/span> At the time t2 – t3ujung A negative, the diode receiving revers voltage, the current will flow RL prisoners revers, this current of only a few mikroamper (), therefore negligible, so that the ends of the RL no voltage.<\/span><\/p>\n

\n From the picture above is referred to as the anode P atoms and N atoms as the cathode.<\/span> If the anode and cathode is charged positively given a negative charge, then the current will flow (lights on), otherwise if the anode and cathode are given a negative charge given a positive charge, the current does not flow.<\/span> Direction of movement is named after the current flowing toward the forward movement or forward direction.<\/span> Direction of movement without this current flow is named direction of motion on or revers direction.<\/span>
