zener diode as voltage regulator class 12

Zener Diode as a voltage regulator. This semiconductor is manufactured in a wide variety of voltages and powers. when the voltage across the zener diode exceeds its zener voltage rating VZ) . To keep the output voltage constant at the desired value in spite of variations in the supply voltage. 3(b) to charge a rechargeable battery of voltage V8 = 10V. Mit Zenerdioden kann ein stabilisierter Spannungsausgang mit geringer Restwelligkeit bei wechselnden Laststrombedingungen erzeugt werden. Observe the nearly constant voltage in the breakdown region. you are here->home->Physics->Class 12->Zener Diode. Nov 25, 2020 - Zener diode as a voltage regulator - Semiconductor Electronics Class 12 Video | EduRev is made by best teachers of Class 12. pn junction and zener diode 12 class project.ppt 1. in DEPARTMENT OF PHYICS MOTHER TERESA SR. SEC. Here, look at the schematic symbol and appearance of a Zener diode. Design a Zener diode voltage regulator circuit as shown in Fig. A Zener diode can limit the voltage across it, making it a voltage regulator! Our mission is to provide a free, world-class education to anyone, anywhere. By designing the regulator here means to find the values of VZ and R. Since the load voltage is to be maintained at 12 V, we will use a zener diode of zener voltage 12 V i.e., The voltage across R is to remain constant at 16 − 12 = 4 V as the load current changes from 0 to 200 mA. By studying these concepts, you will be able to explain Zener diode as a voltage regulator in a better way and solve exercise questions. Furthermore, choosing a Zener diode becomes easy as the required output voltage and the input voltage is known from the beginning. Zener Diode is a general purpose diode, which behaves like a normal diode when forward biased. The image depicts a current versus voltage graph. Here is a link to step by step physics experiment of Zener diode as a voltage regulator and how its made. I happened to check the output of the 12 volt wall transformer and found it was 13.4 volts. Zener diode is connected parallel to the load to make it reverse bias and once the Zener diode exceeds knee voltage, the voltage across the load will become constant. The resistance box is connected as load across the zener diode and the regulated voltage across it is measured using the multimeter. Theory. Therefore, the constant voltage helps Zener Diode as Voltage Regulator. However, this forward flow of current can be reversed if the voltage surpasses a specific value which is known as the breakdown or Zener voltage. Let us say if Zener voltage of 5 V is used then, the voltage becomes constant at 5 V, and it does not change. There is a series resistor connected to the circuit in order to limit the current into the diode. We do not use ordinary junction diode because the low power rating diode can get damaged when we apply reverse bias above its breakdown voltage. Ans. Your email address will not be published. Its property of breakdown voltage which we have discussed earlier plays a key role in voltage regulation.
