Zusammenfassung:PROBLEM TO BE SOLVED: To provide a serial conversion adjusting and modulating device which increases stability and dependability of a high-voltage and specific high-voltage system.SOLUTION: In an adjust voltage principle, one AC current (adjust power supply) controlled by an AC adjust device is serially connected to the AC power supply of a sine wave of one constant voltage (or an adjustable voltage, and a voltage when an AC adjust voltage device is in a phase control is constant). The two power supplies output a periodic wave of a same frequency in which one voltage waveform is continued by a waveform overlapping principal. In a capacitance generating a high harmonic wave, an amount of the high harmonic wave generated by the capacitance of an adjust voltage range (the capacitance of the adjust voltage power supply) only remains from the high harmonic wave generated by adjusting all capacitance in the conventional AC power control circuit, and a content amount of the high harmonic wave is declined significantly.SELECTED DRAWING: None 【課題】高圧・特別高圧電力システムの安定性と確実性の増加する直列変換調圧変圧器を提供する。【解決手段】調圧原理は、一つの定電圧(または調整が可能な電圧で、交流調圧器が位相制御時の電圧は一定である)の正弦波の交流電源(習慣によると定電圧の電源と呼ぶ)に交流調圧器により制御される一つの交流電源(調圧電源)を直列接続する。二つの電源は、波形重畳原理により一つの電圧波形が連続している同周波数の周期波を出力する。高調波を発生させる容量は、従来の交流電力制御回路におけるすべての容量を調整して発生する高調波から調圧範囲(調圧電源の容量)の容量により発生する高調波の量のみ残るようになり、高調波の含有量は大幅に低下する。【選択図】なし
