I believe that many people who have just come into contact with diodes are no strangers to diodes. When it comes to the characteristics of the diode, they can say that it is one-way conductive characteristics blurted out.
The instinctive reaction of the application in the circuit is rectification, but in fact these ideas are wrong people, and to some extent they will hurt themselves.
Because this kind of directional thinking affects the analysis of the working principles of various diode circuits, many diode circuits cannot explain their working principles with unidirectional conduction characteristics.
However, in addition to the unidirectional characteristics of the diode, there are many characteristics, and in many circuits, the unidirectional characteristics can not be used to analyze the working principle of the circuit composed of the diode.
And need to master more characteristics of the diode to correctly analyze these circuits.
