Answer Posted / 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...
