What is the transformation ratio of the high-voltage transformer in the figure? [Copy link]

Use IR2153 to make an electrostatic generator, as shown in the figure The test point of the waveform CH1 in the figure below is the primary side of the high-voltage package, and the test point of CH2 is the two ends of R4 i May I ask: Can you see the transformation ratio of the high-voltage package? (The data given by the merchant for the number of turns of the primary and secondary sides of the high-voltage package is 90/2800) The number of turns is 30, and my understanding is that the transformation ratio = turns ratio = 30 According to the figure, the peak-to-peak value of the CH1 channel waveform is 7V, and the peak-to-peak value of the CH2 channel waveform is 26.8V*4=107; then the transformation ratio = 107/7=15.3! =30; is it different from the turns ratio? But here the primary side is a rectangular wave, and the amplitude side is a triangular wave, so I suspect that my calculation is wrong. PS: The power of the high-voltage package is 100W

Let's not talk about the waveform first, because we don't know where to measure. Just saying, "the primary side here is a rectangular wave, and the amplitude side is a triangular wave" is wrong. The primary side is a rectangular wave. When the magnetic core is not saturated, the waveform output by the secondary side is also a rectangular wave. The principle of the transformer is the principle of electromagnetic induction. Electromagnetic induction is not an electronic circuit. It is incorrect to transform a rectangular wave into a triangular wave in a transformer.

Hello, the primary side test point directly measures the two ends of the primary side, while the amplitude side measures the two ends of the resistor R4. As for why it is a triangular wave, I don't know if it is the influence of the oscilloscope probe.
