What is the function of filter in rectifier circuit?

A filter circuit is one which removes the ac component present in the rectified output and allows the dc component to reach the load.

What is full wave rectifier without filter?

The full-wave rectifier consists of a center-tapped transformer, which results in equal voltages above and below the center-tap. During the positive half cycle, a positive voltage appears at the anode of D1 while a negative voltage appears at the anode of D2. Due to this diode D1 is forward biased.

Are full wave rectifiers easier to filter?

This allows the ac component to be passed through the capacitor more easily. Therefore, the output of a full-wave rectifier is much easier to filter than that of a half-wave rectifier. The greater the load current, the more rapid the discharge of the capacitor, and the lower the average value of output voltage.

What is full wave bridge rectifier with filter?

Like the center tapped full wave rectifier, the output Direct Current (DC) of the bridge rectifier contains small ripples. These small ripples can be reduced if we use the filter at the output. The filter converts the pulsating Direct Current (DC) into pure Direct Current (DC).

What is the primary function of a filter?

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.

What is the ripple factor of full wave rectifier without filter?

1.21
Calculation : Theoretical calculation (without filter) : Ripple factor = √(Vrms/Vdc)2-1=√(Vm/2/Vm/Π)2-1 = 1.21.

Where are full wave rectifiers used?

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.
  • Our home inverters convert AC to DC.
  • LCD, LED TVs.
  • Car Alternator to charge the batteries during the running of the car.
  • LED Driver Circuits.

What do you mean by rectifier filter?

We have learnt in rectifier circuits about converting a sinusoidal ac voltage into its corresponding pulsating dc. The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output.

What is rectifier explain full wave rectifier?

A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC. Unlike halfwave rectifiers that utilize only the halfwave of the input AC cycle, full wave rectifiers utilize the full cycle.

What is the main function of the filter in a rectifier circuit Mcq?

The filter is a device which is used to eliminate the ripple or fluctuation in DC voltages for achieving a complete smooth DC voltage at output.
