I am working on project of controlling speed of 3 phase induction motor. To control the speed of motor I am using thyristor
TYN16-600CT. As I am searching for different research papers and study material on speed control of 3 phase induction motor I found this MATLAB simulation...
In this simulation, I found that there is individual pulse required for each thyristor. This firing pusle is generated using this equation,
t = alpha/omega= alpha/2*pi*f
For, simplicity if
alpha = 30 degree then
My question is, Is it possible to operate all thyristor by applying same pulse??
Can I use below schematic to control speed of motor??
But as I said I have to use thyristor and in this schematic there is use of triac.
So if this schematic can work fine, what changes I have to do to replace triac with thyristor??
