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...

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
by using pump duty, how we will can calculate the motor duty(KW)? is there any standard or formula.
