纹波

Look up and you'll see a water drop ripple headliner, which most likely aids with vehicle acoustics as much as offering visual interest.

查一查，您会看到一个水滴纹波头条新闻，其中最有可能与汽车音响艾滋病多达提供视觉趣味。

Therefore, these converters provide a low-ripple power over broad ranges of input voltage and load current.

因此，这些转换器可提供比输入电压和负载范围广泛的低纹波电流。

To overcome these drawbacks, the application of current mode tri-state modulation technology to the switching power amplifier for magnetic bearings is proposed, as well as its special advantages.

文中首先分析了电流纹波对磁轴承系统的影响，接着分析了电流两态调制技术本身的固有不足及电流三态调制技术在磁轴承开关功放应用中的优势。

Switching power amplifier of magnetic bearing worked in hard switching. To overcome drawbacks of large loss of switching and current harmonic distortion, a parallel resonant DC link soft-switching power amplifier was adopted in this paper.

为克服磁悬浮轴承开关功率放大器工作在硬开关状态时存在的开关损耗和电流纹波干扰严重的缺点，提出一种磁悬浮轴承并联谐振直流环节的软开关功率放大器电路。

For the same core material and at approximately the same current rating, a 10 microhenry inductor will be typically offered at roughly half the size and cost of a 50 microhenry inductor.

例如，用纹波电流驱动一个1A的白光LED (VF≈ 3.5V)，ΔIF需要满足±5%范围内，输入电压12V，频率为500kHz，在电感电流幅度为1.1A时，只能允许使用50mH的电感。

If C1 is too small, it discharges during the D1and D2 nonconducting in terval, and more output ripples result.

它在D1和D2不导通期间C1放电很大，会增大输电压的纹波。

Keeping this in mind, it's time to turn back to our MVP orchestration issues.

牢记这一点，是时候要回我们的纹波业务流程问题。

The peak value of the ripple voltage should be less than the rated voltage.

所施加纹波电压的峰值应小于额定工作电压。

The pump eliminates the effect of channel-length modulation and makes the charging and discharging currents match perfectly in a wide output range to minimize the ripple of the control voltage.

该电荷泵结构可以很好地克服沟道长度调制效应的影响，使充放电电流在宽输出电压范围内实现精确匹配，从而使频率综合器的压控电压纹波很小。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
