When checking the rectifier diode circuit with a meter after use, it was found that the rectifier diode had become sluggish.
Surface mounted rectifier diodes generate heat during operation, and excessive heating can accelerate their service life. Therefore, the cooling system of rectifier diodes is developed.
Generally speaking, the forward voltage drop of fast recovery diodes is small, around 0.4V, while that of ordinary silicon transistors is around 0.6V. To reduce losses, fast recovery diodes are used.

The structure of the rectifier bridge stack was mentioned in the previous draft, one of which is composed of two diodes.
If we find any problems with the rectifier diode, we can also measure it ourselves if we are not professional. Beginners can also use a multimeter. Before testing, first turn the multimeter's conversion switch to the RX1K position in the ohms range, and then short-circuit the red and black probes to zero the ohms.
