WebLoad Commutated Inverter Fed Synchronous Motor Drive is shown in Fig. 10.22. The inverter is a current source inverter employing thyristors T 1 – T 6 . The commutation of inverter thyristor is done by the voltages induced in armature of the synchronous motor. A chopper is used to obtain a variable dc voltage V ds from the fixed source voltage V. http://gn.dronacharya.info/ECEDept/Downloads/QuestionPapers/6th_sem/IntroductionElectricDrives/unit-2/ied_Unit2_Lecture10.pdf
