Peak Inverse Voltage of Center Tap Rectifier
Peak Inverse Voltage Each diode in the full-wave rectifier is alternately forward-biased and then reverse-biased. The maximum reverse voltage that each diode must withstand is the peak secondary voltage Vp(sec). This is…
Center Tapped Full Wave Rectifier Operation
A center-tapped rectifier is a type of full-wave rectifier that uses two diodes connected to the secondary of a center-tapped transformer, as shown in Below Figure. The input voltage is coupled through…
Full Wave Rectifier
A full-wave rectifier allows unidirectional (one-way) current through the load during the entire 360° of the input cycle, whereas a half-wave rectifier allows current through the load only during one-half of the…
Half Wave Rectifier Principle
Half Wave Rectifier : Half-Wave Rectifier Operation The below Figure illustrates the process called half-wave rectification. A diode is connected to an ac source and to a load resistor, RL, forming…
Basic DC Power Supply Circuit
All active electronic devices require a source of constant dc that can be supplied by a battery or a dc power supply. The dc power supply converts the standard AC voltage available…
Difference between ideal diode & conventional diode
An ideal diode is a diode that acts like a perfect conductor when voltage is applied forward biased and like a perfect insulator when voltage is applied reverse biased. So…
Ideal Diode Characteristics
The ideal model of a diode is the least accurate approximation and can be represented by a simple switch. When the diode is forward-biased, it ideally acts like a closed (on) switch,…
VI Characteristic of a Diode
As we know, forward bias produces current through a diode and reverse bias essentially prevents current, except for a negligible reverse current. Reverse bias prevents current as long as the reverse-bias…
Forward Bias & Reverse Bias of a Diode
A diode is made from a small piece of semiconductor material, usually silicon, in which half is doped as a p region and half is doped as an n region with a…
Energy Diagrams of PN Junction & Depletion Region
The valence and conduction bands in an n-type material are at slightly lower energy levels than the valence and conduction bands in a p-type material. Recall that p-type material has trivalent impurities…
