Basic operation of the high-voltage/high-power composition was verified by simulation using MATLAB
as shown in Fig.8. The rating of the synchronous motor is 13.2kV/75MW, 2 pole, 5,000rpm. The main circuit is 2- bank composition (A-bank and B-bank) same as Fig.3. Its AC source voltage is 50Hz/6.9kV, and the voltage ratio of input transformer is 1:1. The capacitor of ZVS commutation circuit is 200
