The above figure shows the circuit diagram of transistor shunt regulator where the transistor is connected in shunt (parallel) with the load hence the circuit is called transistor shunt regulator. The zener voltage VZ of zener
When the zener diode is operated in reverse biased condition at breakdown voltage, the reverse resistance drops to a very low value and the effort of a rapid resistance in zener current together with a rapid decrease
There are some advantages of zener diode shunt regulator are given below, The zener diode shunt is very economic as it is of low cost. It requires only two or three components. It has a very simple
The transformer used for impedance matching. The transformer used for isolate two circuits electrically. It is used to increase or decrease the alternating voltages in electric power applications. The transformer used in voltmeter, ammeters, protective relay etc.
The voltage regulator is a regulator which is designed to automatically convert voltage into a lower, direct current (DC) and constant voltage. It is mainly used to maintain a constant voltage level. A fluctuating DC voltage may
