why we use only sine wave in ac why we do not use other wave
forms
Answer Posted / bikash chandra pal
By virtue of construction & operation of generator, it
possible to generate Sine wave only.
When a non varying flux (fild flux) rotates & cuts the
stator winding(a winding of conductor ) , a sinusoidal
voltage wave induced in stator in turn current.
The appliences(eg Motor etc) has been designed to utilise
the same in the most easiest way with minimum losses.
of course we can generate voltage wave(in turn current)
which is not sine wave simply by variying the field flux.
But what will be the result of that?? Hermonics. which
will contribute increased losses, lesser life span of
equipments because of more heating, if we go in details of
the same , it will be seen that effect of non-sinusoidal
waves is not +ve. it is -ve .
Hence we only use sinusoidal wave(voltage & hence current)
I have just given a try to explain ,saying just whatever
came in my min in first go. if somebody can add some more
value to it please. we all will learn. please
