As we know that IGBT can be controlled in both turning on
and turning off conditions, so we can control the switching
frequency during conversion, hence we would make switching
for very small instant and would get a smooth and less noise
sine wave. while in case of thyristor, we can only control
it in "on" condition, so switching would affect and we can't
get desired smooth and less noise sine wave at output.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
