Answer / suvendu chakraborty
Dear All,
Pls avoid both the answers given above. the correct answer
is :
Rectifier converts AC to DC
Convertor converts AC to Variable DC.
This means Rectifier uses diodes which converts whatever AC
is fed at the input to the DC
Converters uses SCR ( sometime along with diodes )which are
fired accordingly and variable DC is generated by phase
control mechanism

Answer / jaishree gupta
(A)diode are extensively used in rectifier ckt that convert
ac voltage into fixed dc voltage.i/p voltage to the
rectifier could be sigle phase or three phase...
(B)on the other hand converters working can be explained
with the help of their 4 types-
1.ac-dc conveters(also known as controlled rectifier)-
natural commutated thyristors are extensively used.the
average value of o/p voltage can be controlled by varying
the conduction time of thyristors or firing angle delay.the
i/p could be a single or three phase source...
2.ac-ac converters(also known as ac voltage controller)-
these converters are used to obtain a variable ac o/p
voltage from a fixed ac source.in which TRIAC are used and
average value of o/p voltage is controlled by varying the
conduction time of a thyristor or firing angle delay...
3.dc-dc converters(also known as chopper or switching
regulators)-in which transistors are used and average time
of o/p voltage is controlled by varying the conduction time
of transistor...
4.dc-ac converters(also known as inverter)-in which also
transistors are used.the o/p voltage is of the alternating
form.the o/p voltage can be controlled by varying the
conduction time of the thyristors...

Answer / vishnu kumar
A rectifier can just convert a.c to D.C. but the converter
can do both ac to dc and also dc to ac... depending on the
firing angles and such criteria

Answer / joseph
Rectifier means Alternating current(AC) to Direct current(DC) conversion and apply the use of diodes.
A converter can be AC to DC or DC to AC or conversion from one level of either AC or DC to another level.

Answer / benme99
A rectifier converts AC voltage into DC voltage. A
converter is something more general. It describes not only
rectifiers, but also devices that can turn DC into AC or
perform DC-to-DC or AC-to-AC conversion.
Or
converter change one form of supply in to other.that is
from AC to DC, DC to AC(inverter), AC to AC(cylic
converter) with change in frequency.
rectifier convert AC into DC.that rectifier is a kind of
converter. But all the converters are not rectifiers.
In all whole converters makes use of SCR, MOSFET and
transistors, rectifiers is almost always diodes (bridge or
single)

Rectifier Which Converts fixed ac to fixed dc...but Converter converts fixed ac to variable dc depending upom our requirement..
Is This Answer Correct ? | 10 Yes | 1 No |
Answer / sadhitha
Rectifier converts ac to fixed dc using diode (uncontrolled
device)but converter converts ac to variable dc using diode
along with thyristor(controlled device).

Answer / kumar
Rectifier means AC to DC voltege and only used for
diodes.but converter means AC to DC voltage and used for
both diode and thyristors family.
