Abstract :
This paper presents the control techniques for a dual current source GTO inverter (DCSI) in a high power environment. The output current space vector diagram for the DCSI is presented. The important issue of DC current sharing between the two bridges is discussed, and a novel current sharing control scheme based on the use of redundant switch combinations is presented. Harmonic issues are discussed. The ranges of independent control of real and reactive power for different DC power sources are presented.<>
