l am new to this forum and to electronics. l am trying to build a three phase ac soft start for an induction motor using components which are readilly available on the market and would greatly appreciate your help.
Preferably l would like to build this circuit using a phase control ic, and would like to find out which one is the easiest one to use.
Or to use a circuit which will make it possible for zero volatage detection
l would also like to use an opto-triac for isolation and would like to know which one l can use for this particular circuit.
Best regards
Fiso
