چکیده

The steady state analytical performance of a line commutated inverter fed three phase synchronous motor under variable speed condition is presented. The firing pulses for six silicon-controlled-rectifiers of the three phase inverter are generated by the control circuit in proper sequence with the help of synchronizing signal derived from the induced electromotive force of the synchronous machine by using voltage sensor. The analytical 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.
