Figure 1
This one is a high voltage power supply circuit that gives an output of +600V DC. The circuit acts as a full wave voltage doubler and when mains voltage (230V) applied to the input the output DC level becomes nearly 600V DC.
There are only a few components in the design. You can see a fuse connected serially to the input with the R1 resistor to protect the circuit against high voltage transients and high current. Then a filter circuitry consists of coils, C1, C2 and C3 capacitors filters the line voltage. C4 and C5 protect the BY127 diodes against high voltage transients and also reduce inter carrier hum modulation of the R.F picked up by the mains.
C7 and C6 are ample for stabilizing the output DC voltage.

3 years ago: it is a great and magnificent circuit and thank you very much
2 years ago: where do you normally use such big voltages? I guess when you build this circuit, you have to provide a sufficient insulation to avoid damages
2 years ago: if the diodes were not protected by the capacitors, there will always be short circuit or overloading in this circuit...
1 year ago: The rectifier is placed wrong.
Now you have a shortcut during one period.
D2 and D3 must be turned 180°.
