Triple voltage rectifier circuit diagram: In the actual circuit, the voltage on the load is Usc = 2X1.2E2. The highest reverse voltage experienced by rectifier diodes D1 and D2 . DC voltage Uc1 on the capacitor , Uc2= . Circuits and selection components can be designed accordingly.

On the basis of the double voltage rectification circuit, a rectifier diode D3 and a filter capacitor C3 are added to form a triple voltage rectifier circuit, as shown in Figure 5-15. The working principle of the triple voltage rectifier circuit is: in the first half cycle and the second half cycle of e2 , the same as the double voltage rectifier circuit, that is, the voltage on C1 is charged. , the voltage on C2 is charged close to . When the third half is over, D1 and D3 are turned on, D2 is turned off, the current is charged by C1 except D1, and C3 is charged by D3. The charging voltage Uc3 on C3 = e2 peak + Uc2 - Uc1≈ Thus, on RFZ,, the DC voltage Usc=Uc1i+Uc3 can be output. + =3√2 E. , to achieve triple voltage rectification.

In the actual circuit, the voltage on the load Ufz ≈ 3x1.2E2 rectifier diode D3 is also the highest reverse voltage The DC voltage on the capacitor is .

In this way, by adding multiple diodes and the same number of capacitors, it is possible to form a multiple voltage rectifier circuit, see Figure 5-16. When n is an odd number, the output voltage is taken from the upper end: when n is an even number, the output voltage is taken out from the lower end.

It must be stated that the voltage doubler rectifier circuit can only work when the load is light (ie, Rfz is large and the output current is small), otherwise the output voltage will decrease. The higher the voltage doubler, the more obvious the increase in output voltage due to the increase in load current.
