By analyzing the pulse transformer and ideal drive electric current wave, we try to improve the rate of changing-over, discuss the damped oscillation, point out existing circuit design error, and working a new circuit design which can reduce the common circuit circulation and switch loss.
通过对脉冲变压器及理想激励电流波形的分析,如何提高转换速率,阻尼振荡予以讨论,指出目前存在的设计误区,做出减少共态导通与开关损耗的新设计。
It presents the causes of the normal-model noise and common-model noise of the switching mode power supply and methods to restrict the noises.
介绍开关电源的常态噪声和共态噪声产生的原因,以及几种抑制噪声的方法。
