Full wave bridge rectifier diagram

The bridge rectifier is a type of full-wave rectifier that uses four or more diodes in a bridge circuit configuration to convert alternating (AC) current to a direct (DC) current.

How does full wave bridge rectifier work?

How does a Bridge Rectifier work? Bridge Rectifiers use four diodes that are arranged cleverly to convert the AC supply voltage to a DC supply voltage. The output signal of such a circuit is always of the same polarity regardless of the polarities of the input AC signal.

What is full wave bridge type?

The Full Wave Bridge Rectifier This type of single phase rectifier uses four individual rectifying diodes connected in a closed loop “bridge” configuration to produce the desired output.

Where are full bridge rectifiers used?

A Bridge rectifier is an Alternating Current (AC) to Direct Current (DC) converter that rectifies mains AC input to DC output. Bridge Rectifiers are widely used in power supplies that provide necessary DC voltage for the electronic components or devices.

What is the formula of full wave rectifier?

Full wave rectifier: Find out Vrms and ripple factor (r) using formula for full wave rectifier with filter as: Vrms= Vrp-p/4√3 and ripple factor (r) =1/ (4√3 f RLC), where Vrp-p is peak to peak ripple voltage.

What are advantages of a full wave bridge rectifier?

Advantages of Full Bridge Rectifier- The efficiency of full bridge rectifiers is higher than that of half-wave rectifiers. A full bridge rectifier produces a smoother output than a half-wave rectifier. For processing, the full bridge rectifier accepts both positive and negative half cycles of the input AC signal.

What is the application of full wave rectifier?

Full Wave Bridge Rectifiers are mostly used for the low cost of diodes because of being lightweight and highly efficient. The important uses of the full-wave bridge rectifier are given below. Mobile phones, laptops, charger circuits. Uninterruptible Power Supply (UPS) circuits to convert AC to DC.

Why is a rectifier used?

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, which can convert high AC voltage to low DC voltage.

Why 4 diodes are used in rectifiers?

The bridge rectifier consisting of four diodes enables full wave rectification without the need for a centre tapped transformer. The bridge rectifier is an electronic component that is widely used to provide full wave rectification and it is possibly the most widely used circuit for this application.

Which rectifier is best?

For power levels of more than 10KW, three phase bridge rectifier is used because of its simple circuit and less ripple voltage. Also 12 pulse three phase rectifier is the best for high voltage applications because the ripple voltage is very less and it reduces the cost of HV capacitors used for filtering.

What is output of rectifier?

The output of the full wave rectifier is is, essentially a 12 volt DC supply. There will be a small ripple on this supply, but you won't really be able to notice it even if you look at the waveform using the oscilloscope.

What is efficiency of full wave rectifier?

The rectifier efficiency of a full-wave rectifier is 81.2%.

Which diode is used in full wave rectifier?

Bridge Full-Wave Rectifier Four diodes called D1, D2, D3 and D4 are used in constructing a bridge type network so that two of the diodes conduct for one half cycle and two conduct for the other half cycle of the input supply. The circuit of a bridge full wave rectifier is as shown in the following figure.

Why capacitor is used in bridge rectifier?

The current in our full bridge rectifier must pass through 2 diodes on the positive half and 2 on the negative half. So, the voltage drop combines and is around 1.4 to 1.5V. So the output is reduced. However, if we connect a capacitor across the output, we see the output voltage is now higher than the input voltage.

What is rectifier principle?

A rectifier is an electronic device that converts an alternating current into a direct current by using one or more P-N junction diodes. A diode behaves as a one-way valve that allows current to flow in a single direction. This process is known as rectification.

What is rms value in rectifier?

RMS voltage of a half wave rectifier, VRMS = Vm / 2 and Average Voltage VAVG= Vm/π, Vm is the peak voltage. Form factor of half wave rectifier = VRMS / VAVG = ( Vm /2 ) / ( Vm / π ) = π Vm / 2 Vm = 1.57. For a full wave rectifier, the RMS voltage VRMS = Vm / √2 and the average Voltage, VAVG = 2 Vm / π

What is rms value of full wave rectifier?

The rms value is given by the value of the peak voltage divided by $\sqrt 2 $. So in case of a full wave rectifier, the peak value of the sine wave still remains the same. So the rms value is the same as the rms value of the sinusoidal input.

Why it is called bridge rectifier?

The purpose of the Bridge Rectifier is to convert the AC power into DC power. It is the most resourceful rectifier circuit from others. The power conversion in this device is very efficient. We call it a Bridge Rectifier, as it makes a bridge-like circuit by including 4-diodes.

Which rectifier has more efficiency?

For Full wave rectifier maximum efficiency = 81.2% The full-wave rectifier has twice the efficiency of a half-wave rectifier is, that it utilizes both half-cycles of the input.

What are the major disadvantage of full wave rectifier?

Disadvantages of full-wave rectifier:

More complected than half-wave rectifier.
It requires more diodes, two for center tap rectifier and four for bridge rectifier.
PIV rating of the diode is higher.
Higher PIV diodes are larger in size and too much costlier.
The cost of the center tap transformer is high.
