The circuit shown in Figure6 demonstrates the full-wave rectifier design for this part of the lab. During a positive half cycle of the secondary voltage M terminal of the transformer becomes positively charged and N terminal becomes negatively charged. Again for the second half of a. c. input voltage the first two diodes become reverse biased and the second two diodes become forward biased. Theory: Rectification is a process by which alternating voltage is converted into a direct voltage. How these devices can be observed and calibrated virtually. In this way, in both halves of the a. c. input voltage across the load is produced in one direction. In order to produce steady DC from a rectified AC supply, a filter circuit is required. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. This circuit is used for loads which require power control from zero to one-half of full-wave maximum and which also permit (or require) direct current. Circuit connection: . it rectifies both the positive and negative cycles in the waveform. Half Wave and Full Wave Rectifier In Half Wave Rectifier, when the AC supply is applied at the input, a positive half cycle appears across the load, whereas the negative half cycle is suppressed.This can be done by using the semiconductor PN junction diode. c voltmeter may be used.
