「Parametric power Transformer」의 Oscillation 特性에 關한 實驗的 考察[Ⅱ] = An experimental study on the characteristic of 「Parametric power Transformer」

다국어 초록 (Multilingual Abstract)

「parametric power transformer」 which the two cores and windings are 90°relative to each other in space, was manufactured.
The results which have carried cut an experiment on the characteristic of this device were revealed, as follows,
1) The modulation of secondary inductance is m=0.293 and the Q-factor is ??=89.6, therefor it is corresponded with the condition of 「parametric oscillation」, ???
2) Although a distorted input voltage was appled to the primary, the wave-form of the secondary voltage is almost sinusoidal.
3) When capacitor (0.7[㎌]) is connected with this device, the secondary voltage jumps to almost 1, 100[V], and when it is not, only 8[V] appear across the secondary.
