Apparatus: | TINKERCAD - Online simulation Tool Theory: A rectifier is a circuit which converts the Alternating Current (AC) Input power into a Direct Current (DC) output power. 1. Half Wave Rectifier The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply as shown below. 2. Full Wave Rectifier In a Full Wave Rectifier circuit 4 diodes are used, 2 for each half of the cycle. A multiple winding transformer is used whose secondary winding is split equally into two halves with a common centre tapped connection, (C). This configuration results in each pair of diode conducting in turn when its anode terminal is positive with respect to the transformer centre pomt C producing an output during both half-cycles, twice that for the half wave rectifier so it is 100% efficient as shown below. 3.Bridge Wave Rectifier Another type of circuit that produces the same output waveform as the full wave rectifier circuit above, is that of the Bridge Wave Rectifier. This type of single phase rectifier uses four individual rectifying diodes connected im a closed loop “bridge” configuration to produce the desired output. The main advantage of this bridge circuit is that it does not require a special centre tapped transformer, thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge network and the load to the other side as shown below. x Shri Vile Parle Kelavani Mandal's -_ DWARKADAS J.
