Diodes are often used in circuits, but we will find that the diodes used in many circuits are basically connected in series. Let's take a look at how the series connection works.

When the diodes are connected in series, what is the cut-off voltage and voltage distribution? Because when the diodes are connected in series in a static state, it depends on the stability. If there is no better effect, a hydraulic resistor must be used. When the cut-off voltage is greater than 1500 volts, a parallel resistor must also be added to separate the voltages. Although many beginners are very familiar with diodes and know their unidirectional conductivity, many of their uses in circuits are for rectification. In addition, it can also be seen that there are still many such uses in switching circuits.

Diodes can be made into simple DC voltage stabilizing circuits, which can be made at low cost and are widely used. In layman's terms, we can see that this simple voltage stabilizing circuit can stabilize the current and voltage after being connected in series. However, the principle of this DC circuit can also be seen in the arc. It is precisely because AC is converted into DC, and a circuit that converts AC into DC through filter capacitors and resistors to reduce voltage can be formed, and it is still used very frequently.
The switching circuit characteristics of the combination of diode and transistor are still very good, that is, the switching diode is in the conducting state as long as there is forward voltage, and it is in the off state when there is reverse voltage. Using this feature, the switching circuit can be stroked, and the speed is faster. Moreover, the internal resistance is relatively small when it is turned on, and the resistance is very large when it is turned off. The effect of use is still very obvious. When used in the circuit, it can be seen that the inductor and capacitor are connected in parallel, which can form a resonant circuit. After the diode is connected in series, the access and disconnection of the capacitor can be controlled to form a switching circuit. In short, in the use of diodes, whether used in detection circuits or compensation circuits, they are very good.
