The Rectifier is an electronic device, which converts an AC waveform(Usually a Bi-directional waveform with Zero Average value) to a Pulsating DC waveform (Uni-directional waveform with Nonzero Average value). As AC wave (Sinusoidal) has two half cycles, namely - Positive Half cycle & Negative Half cycle If a Rectifier does it's operation only in one half of the cycles, it is known as Half Wave Rectifier. Similarly, If a Rectifier does it's operation in both the half cycles, it is known as Full Wave Rectifier.

∙ 15y agoA rectifier turns AC voltage into DC voltage. You typically get AC voltage from the grid (e.g. 230V in Europe) or from electrical generators, but you need DC to operate any kind of electronics. That why at the input of devices (e.g. computer, radio, TV, all kind of electrical motors, battery charging, ...) you always need a rectifier unit.

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.
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.
Difference between 4 diodes and 2 diodes rectifier?
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier *********************************************************** A two-diode rectifier is not always a centre-tap rectifier. If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage. (But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)

What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?
They both have the same current.
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......
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 is the circuit diagram of half wave rectifier?
Just one diode.
Why capacitor used in rectifier circuit?
To smooth the output of the pulsating DC.
Which electronics circuit gives unidirectional current or wave form?
A rectifier circuit produces a unidirectional wave form.
What are the distributed and lumped circuit?
The circuit is callaed lumped circuit whose elements can seprate(eg rectifier circuit in pcb). but in the distributed circuit we can seprate the elements from the circuit(eg transmision lines)
