초록

This paper presents the novel control and analysis of GTO-CSC. The control method is based on the linearization of an optimal modulation strategy so that the turn-on-periods of the GTO switches can be computed in real-time for any specified modulation index. These PWM patterns allow to produce minimal ac line current low order harmonics of ac line current and low switchings. Finally, the computer simulation results are presented to verify the theoretical analysis.
