Pulse Multiplication of 6-Pulse Thyristor Converter with Simple Auxiliary Circuit

간단한 보조회로 추가에 의한 6-펄스 싸이리스터 컨버터의 다펄스화

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.
