変化域で励磁電流を遮断し、振幅が変化した刺激パルス
を生成する方法しかなかった。Biostimulation devices such as low frequency therapy devices and interference wave therapy devices utilize inductors or transformers and are equipped with means for generating stimulation pulses by intermittent excitation current flowing through them. The only way to add strength or weakness is to cut off the excitation current in the time constant variation region of the excitation current in the unsaturated region of the inductor H, and generate stimulation pulses with varying amplitudes.
但しこの方法では、遮断時に生ずる逆起電力が励磁電流
を遮断する時の変化量にも比例する為、理論上無限大に
達することから、予め供給電圧を制御することか要求さ
れた。However, in this method, the back electromotive force generated at the time of cut-off is proportional to the amount of change when the excitation current is cut off, so it theoretically reaches infinity, so it was required to control the supply voltage in advance.
