What is the diode voltage regulator?
The diode voltage controller is a voltage controller in which one diode acts as a device for voltage control. Like the conventional voltage regulator of the integrated circuit (IC), the diode serves in the circuit to take over the changing input voltage and convert it to specific constant direct currants (DC). The diodes work very well as a control device for the voltage of the regulatory device due to their logarithmic characteristics, that they have very minimal voltage changes, despite relatively significant current changes, thus providing good stability in the circuit when the construction restriction is met. bias. It is a method in which the anode of the diode, its positive guidance, is associated with the soil power, and the cathode, its negative guidance, is associated with the positive side of the power supply. When this happens, the power supply triggers the voltage through the diode equal to the maximum evaluation of the diode voltage. Maximum voltage evaluation is the voltage that is lowered via the zener diode when it is connected in the reverse distortion in the circuit, if jE Power voltage greater voltage. This voltage evaluation is essential in designing the regulation of the perimeter voltage, as it decides on the regulated voltage output.
For example, if there is a power supply of 10 volts and a zener diode with a maximum voltage rating of 5.1 volts, a dimension diode drops 5.1 volts. The component located in parallel will also receive the same regulated voltage output, as the circuits observe the rule that all components in parallel receive the same voltage. In this way, the diode voltage regulation for the circuit is achieved.
Another rule in creating the circuit of the diode voltage controller is for one on the market and a resistor before the diode. The resistor can be and is usually always placed in front of the diode, so if there is an excessive voltage, it drops through the resistor and does not burn a zener diode, which can be drawn defective if it is supplied to an excessive supply voltage. In the example of power supply 10 volts and ZenerovThe LEDs with a maximum voltage rating of 5.1 volts would be sinking by 5.1 volts and the remaining 4.9 volts would be immersed through the resistor, so not all 10 volts after storage. Thus, the resistor in front of the Zener LED acts as a safety device to drop excessive voltages over it so that the Zener diode does not get more voltages than what is necessary.
Another way of connecting the zener diode in the perimeter for voltage control, albeit less commonly used, combines it in the method called forward distortion. This is the method in which the diode anode is associated with the positive side of the power supply and its cathode is Conna's country of power. In such an arrangement, the diode drops a drop in operating voltage, which is usually about 0.7 volts. This is not such a popular method, because only a slightly lower voltage decreases than the voltage issued by the supply source and is not flexible in different value ranges because they are maximum voltage evaluation.
diode voltage control can work well as furnishedThe voltage, but when the accuracy is key, the IC voltage regulator, which contains more built -in control mechanisms, is a better choice. If the diode voltage controller contains sufficiently large shifts in the current, it can cause a different voltage. However, if accuracy is not very important, diode voltage controllers may be a good choice.
