An electronic circuit or electronic device that is used to generate periodically oscillating electronic signal is called as an electronic oscillator. The electronic signal produced by an oscillator is typically a sine wave or square wave. An electronic oscillator converts the direct current signal into an alternating current signal. The radio and television transmitters are broad casted using the signals generated by oscillators. The electronic beep sounds and video game sounds are generated by … [Read more...]
Zener Diode as Voltage Regulator
A Zener diode is a type of semiconductor diode.

Rectifier Diode : Circuit, Biasing and Its Applications
A basic semiconductor, in that there is the presence of two terminals in which one is preferred as a cathode and the other as an anode. It is formed by the two different materials referred to as p-type and n-type. Generally, it is termed as p-n junction diode. As it is application-oriented it is also referred to as rectifier diode. The main purpose of this p-n junction diode is that it is used for the conversion of the applied alternating current (AC) into direct current (DC). This process of … [Read more...]
Ripple Factor for Half Wave and Full Wave Rectifiers
As already known the purpose of the rectifier is to convert alternating current (AC) into direct current (DC). It is the basic unit of any DC supply. The designing of the rectifier and its suitability for practical applications is dependent on the characteristics of that particular rectifier. Its characteristics include RMS value, average output value, ripple factor, peak inverse value and so on. After the completion of the process of rectification, the output DC generated consists of some AC … [Read more...]
Full Wave Rectifier Working and Its Applications
The purpose of the rectifier is to convert alternating current (AC) to direct current (DC). As in the half-wave rectifier, the rectifier output DC consists of AC components or ripples in it. To overcome this filter can be connected across the load so that the ripples can be reduced but this kind of circuitry is suitable for low power required applications. To overcome the problem of the half-wave rectifier, the model of the full-wave rectifier circuit is developed. In full-wave rectifier, full … [Read more...]
Half Wave Rectifier : Working and Its Characteristics
The purpose of the rectifier is to convert alternating current (AC) to direct current (DC) that is to undergo rectification. As the diode used in this process allows the flow of current in a unidirectional manner. Basing on this property of the diode the various types of rectifiers are designed. From the number of diodes used in the circuit the classification of rectifiers is done. Basically, the half-wave rectifier can be designed by using a single diode termed as single-phase rectifier. But if … [Read more...]
