Abstract :
A new pulse multiplication technique based on 6-pulse thyristor converters is proposed in this paper. With the proposed technique, 12-pulse, 18-pulse and 24-pulse operations have been obtained both on the input current and on the output voltage. A control strategy over the whole range of phase angle is provided along with sophisticated input current and output voltage analysis. Experimental results from a laboratory prototype verify the proposed theory
