The auxiliary circuit is composed of an auxiliary switch, a coupled inductor (flyback transformer) and a feedback diode.

辅助电路由辅助开关管、耦合电感(反激变压器)和反馈二极管构成。

Other output voltages are possible by adjusting the transformer turns ratio and value of Zener diode VR2.

其它输出电压是可能的，经过调整变压器匝数比齐纳二极管VR2和价值。

And the diode clamp circuit introduced in the transformer primary can apparently restrain from the peak voltage resonance in the rectified diodes.

在变压器的初级使用二极管钳位电路，可以有效地抑制变压器次级的寄生振荡。
