Principles for selecting rectifier diodes and capacitors in rectifier bridge circuits

How to choose rectifier diodes for rectifier bridge circuits, of course, there are certain principles when selecting rectifier diodes.

1. When the conduction voltage is low, select a germanium diode;

2. When the conduction voltage is high, select a silicon diode;

3. When reverse current is low, silicon diodes should be selected;

4. When the reverse breakdown voltage is high, choose a silicon diode;

5. When high temperature resistance is required, silicon diodes should be selected;

6. When the conduction current is high, choose a surface contact diode;

7. When the operating frequency is high, select a point contact diode.

In engineering design, the value of the filtering capacitor is generally calculated from two entry points.

After reading it, did you notice that there is a phenomenon in the selection of rectifier bridges, which is that the selection should be based on certain parameters and will change with the variation of parameters.
