How transistor shunt regulator is work?
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
Block diagram of transistor shunt voltage regulator
The block diagram of transistor shunt voltage regulatoris shown in above figure. The transistor shunt voltage regulator is a control element connected in parallel with the load due to this circuit is called a shunt voltage
Zener diode as a voltage regulator
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
Application of zener voltage regulator
There are some important applications of zener voltage regulator are given below, The zener voltage regulator is used in the emitter follower regulator. It is used with a small load current range over which the output DC
Advantages and disadvantages of zener diode shunt regulator
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
Advantages and disadvantages of a transistor shunt regulator
There are some advantages of transistor shunt regulator are given below, The transistor shunt regulator has a good efficiency for small load currents. It has ease to reject short circuit. The voltage regulation is good. It has
What is a trimmer capacitor?
It is a variable capacitor which has the facility to vary its capacitance value, but frequently once variation is sufficiently, it is known as the trimmer capacitor. It is also called as simply trimmer or padder. In
IC 555 timer (integrated circuit )
The 555 timer IC is an integrated circuit which is used in variety of timer, pulse generations and oscillators applications. The IC 555 timer got its name by three 5kΩ resistor in series used in the internal
Construction of PVC gang capacitor
The PVC gang capacitor is a type of variable capacitor. It is a gang capacitor which uses the PVC material as a dielectric medium, is called a PVC gang capacitor. This capacitor has a very small in
Construction of air ganged capacitor
The basic construction of air ganged capacitor is as shown in fig. It consists of two sets of aluminium plates separated from each other by air. These metal pates may be rotary or concentric type. The rotary
