What is a full wave rectifier circuit? Answer: If the structure of the rectifier circuit is adjusted, a full-wave rectifier circuit that can fully utilize the power can be obtained. The figure below is an electrical schematic of a full-wave rectifier circuit. The full-wave rectification circuit can be considered as a combination of two half-wave rectification circuits. The center requirement of the secondary winding of the transformer leads to a tap, which divides the two sets of coils into two symmetrical windings, and then extracts two voltages e2a and e2b of equal size but opposite polarity to form e2a, D1, Rfz and e2b, D2, Rfz, Two energized circuits. The operating principle of the full-wave rectifier circuit can be illustrated by the waveform diagram shown in Figure 5-4. Between 0 and π, e2a is a forward voltage for D1, D1 is turned on, and a positive and negative voltage is obtained on Rfz; e2b is a reverse voltage for D2, and D2 is not conductive (see the figure below at π-2π). During the time, e2b is forward voltage for D2, D2 is turned on, and the voltage obtained on Rfz is still positive and negative; e2a is reverse voltage for D1, D1 is not conductive (see the following figure for repeating, because two The rectifying elements D1 and D2 are alternately conducting, and the resultant load resistance Rfz has a current in the same direction during the positive and negative two-half-week effect periods, as shown in the figure, so it is called full-wave rectification, and full-wave rectification is not only The positive half cycle is utilized, and it is also wonderfully advantageous to use the negative half cycle, and then the rectification efficiency is greatly improved (Usc = 0.9e2, which is twice as large as that of the half wave rectification). The full-wave splicing circuit shown in Figure 3 requires the transformer to have a secondary center tap that is symmetrical at both ends, which causes a lot of trouble in production. In addition, in this circuit, the maximum reverse voltage that each rectifier diode is subjected to is twice the maximum value of the secondary voltage of the transformer, so a diode capable of withstanding higher voltages is required.
