Voltage Stabilisation | Zener Diode

Whats is Voltage Stabilisation A rectifier with an appropriate filter serves as a good source of d.c. output. However, the majordisadvantage of such a power supply is that the output voltage changes with the variations in the input voltage or load. Thus, if the input voltage increases, the d.c. output voltage of the rectifier also … Read more

Voltage Multiplier | Half Wave Voltage Doubler

What is Voltage Multiplier ? With a diode, we can build a rectifier to produce a d.c. voltage that is nearly equal to the peak valueof input a.c. voltage. We can also use diodes and capacitors to build a circuit that will provide a d.c output that is multiple of the peak input a.c. voltage. … Read more

Filter Circuit | Types of Filter Circuits

What is Filter Circuits ? Generally, a rectifier is required to produce pure d.c. supply for using at various places in the electronic circuits. However, the output of a rectifier has pulsating *character i.e. it contains a.c. and d.c. components. The a.c. component is undesirable and must be kept away from the load. To do … Read more

Nature of Rectifier Output | Ripple Factor | Comparison of Rectifiers

Nature of Rectifier Output It has already been discussed that the output of a rectifier is pulsating d.c. as shown in Fig. 6.37. In fact, if such a waveform is carefully analyzed, it will be found that it contains a d.c. component and an a.c. component. The a.c. the component is responsible for the *pulsations … Read more

Faults in Centre Tap Full Wave Rectifier

Faults in Centre Tap Full Wave Rectifier The faults in a center tap full-wave rectifier may occur in the transformer or rectifier diodes. Fig.6.36 shows the circuit of a center-tap full-wave rectifier. A fuse is connected in the primary of the transformer for protection purposes. We can divide the rectifier faults into two classes viz. … Read more

what is Semiconductor Diode | Properties of Diode

What is Semiconductor Diode It has already been discussed in the previous article that a pn junction conducts current easily when forward biased and practically no current flows when it is reverse biased. This unilateral conduction characteristic of pn junction (i.e. semiconductor diode) is similar to that of a vacuum diode. Therefore, like a vacuum … Read more

Half Wave rectifier | Properties | Frequency| Ripples

What is a Half Wave Rectifier? A half-wave rectifier can be explained as a type of rectifier that only passes one half-cycle of an AC voltage waveform to pass, blocking the remaining half-cycle. Half-wave rectifiers are normally used to convert AC power to DC power, and only require one diode to construct. A simple Half … Read more

What is Diode | Types | Properties | Applications

What is diode ? A diode can be discussed as a two-terminal electronic device that only conducts current in one direction (so long as it is working within a required voltage level). An ideal diode always has zero resistance when it is forward biased or one direction, and infinite resistance in the reverse bias. basically … Read more

Full wave Rectifier | Properties | Efficeince | Ripples

FULL WAVE RECTIFIER: In full wave rectifier, current flows through the load in the same direction for both half cycles of ac input voltage .it allows unidirectional (one way) current through the load during the entire 360 degrees of the input cycle, whereas a half-wave rectifier allows current through the load only during one half … Read more
