Abstract :
A novel and simple scheme for use in three phase firing circuit for wire ac voltage controller system is proposed. This scheme enables the firing circuit to adjust itself against any phase and/or sequence alterations. This feature leads to elimination of the manual adjustment usually needed in such cases. The scheme can also detect if the system contains faulty thyristors. Experimental results are given to verify the principle of operation of the proposed scheme
