This paper presents the simulation works of a line commutated inverter fed three phase synchronous motor under variable frequency condition. The triggering pulses for six thyristors of the three phase inverter are generated by the control circuit in proper sequence with the help of synchronizing signal derived from the induced emf of the synchronous machine by using voltage sensor. The simulation results indicate that a three-phase synchronous machine supplied by an inverter with the excitation winding connected in series to the input of the inverter provides similar characteristics of dc series motor.
