Hi all,

I am currently building phase angle controller by using the thyristor. I was wondering how can I choose the suitable value for the resistive and inductive load for the rectifier? Is it something to do with the time constant of RL load? The frequency of operation is 50Hz. Thank you all.

 

The cart is before the horse. The load will require some range of current. You select the rectifier/thyristor based on the current it has to pass, plus the peak line voltage.
