Abstract :
To obtain a high-power DC current source, the SCR bridge is frequently used. The reactive power consumption, the line current absorption with high harmonic distortion combined with important filters, and a slow dynamic response are the main disadvantages of the previous actuator. An alternative approach is to use a 6 GTO structure associated with a three-phase line LC filter. A current control loop combined with the PWM space vector modulation synthesis assume an optimal input-output dynamic performance and a high line-current spectrum quality. Simulation results are discussed and demonstrate the effectiveness of the entire system behaviour
