To achieve high oscillation peaks, the design of the transformer has to be set to high reflected voltage.

要达到比较高的振荡电压峰值，变压器的反射电压必须设置的比较高。

For example, the peak at 20 MHz in the spectrum is caused by the parasitic oscillation due to the output capacitance of the MOSFET and the leakage inductance of the transformer.

举例说明，20兆赫兹的峰点是钳位过程结束后主要由场效应晶体管输出电容和变压器漏感引起的寄生振荡产生的。
