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。
And the diode clamp circuit introduced in the transformer primary can apparently restrain from the peak voltage resonance in the rectified diodes.
然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。
However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit.
钳位电路用于某些数据设备可使接收器输出为常量，并且可在没有收到数据信号时避免噪音干扰。
A clamp is used in some data sets to hold receiver output constant and avoid troublesome noise interference when no data signals are being received.
