Abstract
A dual GTO current source power converter topology with sinusoidal inputs is proposed for high power applications. The sinusoidal input current is realized by using PWM 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 Hz or 420 Hz. The combination of these switching patterns provides a full range control over the DC 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.Keywords
