☑ Make Zener Diode Voltage Regulator

But when it is reverse biased above a certain voltage known as zener breakdown voltage or zener voltage or avalanche point or zener knee voltage the voltage remains constant for a wide range of current. The circuit arrangement and calculation is same as the above reference circuit.

But the connections are such that the power flow to the load side is not cut off even when the voltage exceeds the safety limits.

Make zener diode voltage regulator. The zener voltage regulator consists of a current limiting resistor rs connected in series with the input voltage vs with the zener diode connected in parallel with the load rl in this reverse biased condition. Probably the simplest type of voltage regulator is the zener shunt stabilizer which works by using a basic zener diode for the regulation as demonstrated in figure below. The zener diodes have a voltage rating equivalent to the intended output voltage that may be closely match the desired output value.

The stabilized output voltage is always selected to be the same as the breakdown voltage vz of the diode. As the zener diode is connected parallel to the load the voltage across the load will be always equal to the zener voltage. To operate zener diode in reverse region apply voltage greater than reverse breakdown voltage vz to it.

The 12v power supply drops across the 1kw resistor and the zener diode. Zener voltage regulator circuit. You can make zener diode as voltage regulator by operating it in reverse breakdown region where voltage vz remains fairly constant even though iz changes.

Zener diode is a general purpose diode which behaves like a normal diode when forward biased. This particular zener diode in use has a breakdown voltage of 51v. This circuit uses a zener diode to provide a regulated output to the load side protecting the circuit.

The voltage difference between the input voltage v s and v z will be dropped across the resistance r. The above circuit is the perfect setup to make a zener diode voltage regulator. Zener diode voltage regulator.
