What are voltage doublers used for?
A voltage doubler circuit outputs a DC voltage that is double the peak value of the AC input voltage, without using a transformer. There are many electrical design situations where an AC voltage signal is available (or can be created), but a larger DC voltage is needed for the circuit.
What is Delon circuit?
The Delon circuit uses a bridge topology for voltage doubling; consequently it is also called a full-wave voltage doubler. This form of circuit was, at one time, commonly found in cathode ray tube television sets where it was used to provide an extra high tension (EHT) supply.
Why voltage multipliers are required?
The advantage of “Voltage Multiplier Circuits” is that it allows higher voltages to be created from a low voltage power source without a need for an expensive high voltage transformer as the voltage doubler circuit makes it possible to use a transformer with a lower step up ratio than would be need if an ordinary full …
Whats is a transistor?
A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals. Transistors consist of three layers of a semiconductor material, each capable of carrying a current.
What is ripple factor?
The ripple factor, defined as the ratio of the rms value of the ac component to the dc component, increases with the firing angle. From: Control in Power Electronics, 2002.
What is rectifier used for?
A rectifier is used for powering appliances Using a rectifier in the power supply helps in converting AC to DC power supply. Bridge rectifiers are widely used for large appliances, where they are capable of converting high AC voltage to low DC voltage.
What is clipper circuit?
In electronics, a clipper is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level. A clipper does not distort the remaining part of the applied waveform.
What is clamper circuit?
A clamper is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined value by shifting its DC value. The clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as to place the peaks at the reference level.
What are the two basic categories of voltage regulations?
There are two main types of voltage regulators: linear and switching. Both types regulate a system’s voltage, but linear regulators operate with low efficiency and switching regulators operate with high efficiency.
Why is transistor used?
Transistors are commonly used in digital circuits as electronic switches which can be either in an “on” or “off” state, both for high-power applications such as switched-mode power supplies and for low-power applications such as logic gates.
How do transistors work?
A transistor consists of two PN diodes connected back to back. It has three terminals namely emitter, base and collector. The basic idea behind a transistor is that it lets you control the flow of current through one channel by varying the intensity of a much smaller current that’s flowing through a second channel.
What is ripple factor and why it is so important?
Ripple Factor definition: The ratio of r.m.s. value of a.c. component to the d.c. component in the rectifier output is known as the ripple factor. Ripple Factor is very important in deciding the effectiveness of rectifier output. The smaller ripple factor describes the more effectiveness of that rectifier.
