Abstract

An analysis has been made about the performance of the switching-mode amplifier which can improve its efficiency higher than class C in audio amplification, and the improvement of characteristics and constitution in using it for modulator circuits was considered. As a result, the linearity of modulation up to 97% and the frequency response keeping flat up to 7, 200Hz have been observed.

低周波增幅을 C級以上의 效率로 實現할 수 있는 스위칭 모우드 增幅器의 性能을 解析하였고 變調器로 使用하기 위한 回路構成과 얻어지는 特性改善에 關하여 考察하였다. 그 結果 變調度 97〔%〕까지의 直線性, 7,200〔Hz〕까지의 平坦한 周波數特性을 確認할 수 있었다.
