What is the necessity of a filter in a rectifier circuit?
ShaunMarshgp7659
You use filters at the output of a rectifier to smooth out the pulsating DC. With no filter, the output would pulse between peak value (less diode forward drop) and zero. With a simple capacitor, the output would pulse between peak value (less diode forward drop) and some value that is the intersection between the discharge curve for the capacitor and the next forward conduction time of the diode. With a more complex filter, the output is progressively filtered, but that is beyond the scope of this question.

∙ 8y agoDC means flat line voltage/current. When converting AC to DC what a rectifier does is to simply re direct the -ve the voltage/current into the load in such that they follow the same path as the +ve voltage/current. So the output will be filled with half-sinusoidal "Bumps"......which doesnot qualify as a DC supply(as it should be, ideally, flat lined).
So a capacitor based filter is used to level out the output.....by arranging the RC values of the ckt such that there is quick charging and slow discharging...the better designed RC ckt will minimize the differential between the lowest voltage and the highest voltage output. And that is the basis of it...to NOT let the load ckt handle large differences in input voltage, which is bad for any system.

What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit
What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?
They both have the same current.
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
What is the major effect of replacing the two diodes with resistor in bridge rectifier circuit?
Its no longer a rectifier and the resistors may catch fire.
What does the out put wave form looks in a rectifier?
A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.
Why capacitor is used in circuit board?
use as coupling in some circuts and and as a filter in rectifier circuit. use as DC current blocking.
Block diagram of smps?
A block diagram of SMPS has a main filter, primary rectifier, and power switch. It also has an output transformer, secondary rectifier, smoothing circuit, and controller.
What is a rectifier with a single capacitor filter suitable to supply?
A circuit that doesn't require a lot of filtering such as a charging circuit for a battery. In a single capacitor filter, the sine wave or AC doesn't get completely eliminated.
What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit
What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?
They both have the same current.
Why the filter used in rectifier circuit?
Filter capacitors smooth out the pulsating DC. Without the capacitors, the pulsating DC drops to zero at the AC crossing point, unless it is a three phase rectifier. Sometimes, that is sufficient. Sometimes, they are followed up with a regulator circuit that further stabilizes the DC.
What circuit is to be added to a full wave rectifier to produce a smooth DC?
put capacitor parallel on load (peak rectifier) or add low frequency pass filter (composed of L & C) to remove AC components
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
What is the effect of an RL circuit in half wave rectifier?
The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .
What is the opposite of a rectifier?
The electronic circuit that does the opposite function of a rectifier is called an inverter. It converts any DC signal to AC.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
Natural commutation is used in which kind of circuit?
phase controlled RECTIFIER circuit used Natural Commutation......
