摘要
A dual gate-turn-off thyristor current-source converter topology with sinusoidal inputs is proposed for high-power applications. The sinusoidal input current is realized by using pulsewidth modulation techniques to eliminate 11th and 13th harmonics and a transformer to cancel 5th, 7th, 17th, and 19th harmonics. Three switching patterns are proposed with a switching frequency of 360 or 420 Hz, The combination of these switching patterns provides a full-range control over the de output current. Resonant modes of the proposed system are identified, and the criterion for the line capacitor design is provided. Simulation and experimental results are given to verify the theoretical analysis.
