Zener Diode As Voltage Regulator Experiment Pdf. To draw the characteristic curve of a zener diode and to determine its reverse breakdown voltage. 2 zener diode characteristics aim:
EXP5 the Zener Diode as a Voltage Regulator Diode from www.scribd.com
Using the measured values, calculate the value for current across r, ir, current across rl, il, and current across the zener diode, iz. You must also design a circuit that demonstrates the operation of a 7 v ± 5% loaded zener regulator powered by a 12 v dc voltage source. Change the rheostat value from maximum to 0 by the interval 100.
Name Quantity Name Quantity 1 Zener Diode 1(One) No.
Zener reverse current remains low until vr reaches the zener voltage (vz) rating of the component. With your lab partner, brainstorm on the following ideas: A zener diode functions as an ordinary diode when it is forward biased.
To Find Zener Break Down Voltage In Reverse Biased Condition.
Name qty zener diode resistor 1k 1 1. Apparatus zener diode, resistor, variable dc power supply, milliammeter, voltmeter, rheostat, wire. Heavy doping alters the reverse characteristics.
To construct a zener diode voltage regulator. Basic information when a sufficiently large reverse bias voltage is applied to a zener diode, the reverse current will suddenly increase. The semiconducting silicon material used in the zener diode as voltage regulator experiment helps it function in the forward as well as reverse voltages without breakdown.
There Is A Typical Flow Of Current From Anode To Cathode In A Zener Diode.
To calculate % line regulation 3. 2 zener diode characteristics aim: By passing a small current through the diode from a voltage source, via a suitable current limiting resistor ( rs ), the zener diode will conduct sufficient current to maintain a voltage drop of vout.
Applications Of Pn Junction Diode:
Zener diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. Zener diode, resistor, variable dc power supply, milliammeter, voltmeter, rheostat and wire. To draw the characteristic curve of a zener diode and to determine its reverse breakdown voltage.
