i am swathi, b.tech 4th year.
In smps(switched mode power supply)we are using
diodes,mosfets,igbts for controling of current.
And my question is why we did not use thyristors(scr)? it
is also act as a switch,then what is the drawback of scr as
compared to above transisters> if we use the scr,then what
is happening ? plz give reply as soon as possible bcoz i
am doing project on smps. plz frnds i want ans for

Answer Posted / prasad,clp(power)
Hi dear this is prasad from clp (power)...we can use
thyristor(scr) but for scr we have to design firing angle
circuit separatly,we have to check whether scr is
triggering or turning on exatctly as per our requirements
or not and for high power applications it is better to
diodes,mosfet,igbts..in these we wont face firing angle
circuit design problems...bocz for the SCR firing circuit
is the heart hope so....
