The aluminum oxide rectifier shares the full-wave rectifier circuit with you

  If the structure of the rectifier circuit is adjusted, a full-wave rectifier circuit that can make full use of electrical energy can be obtained. Figure 5-3 shows the electrical schematic diagram of a full-wave rectifier circuit.

  A full-wave rectifier circuit can be seen as a combination of two half-wave rectifier circuits. A tap needs to be drawn out in the middle of the transformer secondary coil to divide the secondary coil into two symmetrical windings, so as to draw out two voltages e2a and e2b of equal size but opposite polarity, forming e2a, D1, Rfz and e2b, D2, Rfz, two energizing circuits.

  The working principle of the full-wave rectifier circuit can be illustrated by the waveform diagram shown in Figure 5-4. In the range of 0~π, e2a is a positive voltage to Dl, D1 is on, and a positive and negative voltage is obtained on Rfz, and e2b is a reverse voltage to D2, and D2 is not on. In the time of π-2π, e2b is a positive voltage to D2, D2 is on, and the voltage obtained on Rfz is still positive and negative, and e2a is a reverse voltage to D1, and D1 is not on.
