共模电感是用于抑制电路中共模干扰的一种电感器件。共模干扰是指在电路中同时影响两个信号引线（正负）的干扰信号，通常是外部电磁干扰信号的注入。本文中音特电子将为大家介绍如何选型共模电感。

选择共模电感需要考虑以下几个因素：

1. 频率范围：共模电感的频率响应需要覆盖待抑制的干扰信号频率范围。

2. 额定电流：共模电感的额定电流应大于实际应用中的最大共模干扰电流。

3. 电感值：根据共模电感在线性区的电感值来选择，一般应满足抑制共模干扰的要求。

在选择开关电路中的共模电感时，还需考虑以下因素：

1. 频率范围：共模电感的频率范围需要覆盖开关频率范围。

2. DC电阻：共模电感的DC电阻需要尽可能小，以避免功耗过大。

3. 尺寸：尺寸越小越好，以满足现代电子设备尺寸要求。

4. 高频性能：共模电感的自谐振频率需足够高，以避免在高频开关电路中产生不必要的振荡。

总之，选型共模电感需要综合考虑频率范围、额定电流、电感值以及电感的尺寸和高频性能等因素，以满足具体应用的要求。

【经验】以欧创芯OC6800B为例介绍升压DC-DC电路的布线规则

由于电路中存在电感，MOS，二极管等开关器件，同时PCB上的走线存在寄生电感，寄生电容等参数，在开关器件工作的时候，不合理的布局和布线，会引起开关高频的干扰、电参数特性的失衡和不可逆的损伤等，比如输出电压波动大、动态特性负载变差、纹波变化大、系统工作状态不稳定和芯片失效等。本文以欧创芯OC6800B为例分析升压DC-DC芯片应用基本的布线规则。

SiC MOSFET缓冲电路设计方法

与传统的功率半导体相比，SiC MOSFET的开关速度更快，因此其电压和电流变化更急剧。这使得器件自身的封装电感和外围电路的布线电感等的影响变大（已经不容忽视），最终会导致较大的浪涌。关于这种浪涌的抑制方法，我们已经介绍过其中一种，即缓冲电路的增加方法和设计方法。

【经验】在开关电源中，纳米晶共模电感具备比铁氧体磁芯共模电感更加优良的特性

在开关电源中，由于电源在工作过程中会产生的高di/dt和高dv/dt，它们产生的浪涌电流和尖峰电压会形成了干扰源。在EMI滤波电路中，共模电感主要负责滤出两条入线之共模干扰信号。Nippon Chemi-Con目前生产的纳米晶共模电感主要有FL和FM两个系列，额定电流范围1-30A。

封装寄生电感是否会影响MOSFET性能？

在处理电路板布局和器件封装产生的寄生电感时，快速开关器件接通和关断控制是关键问题。特别是，封装源极寄生电感是是器件控制的关键因素。在本文中，杰绅电感提出了一种用于快速开关超结MOSFET的最新推出的TO247 4引脚器件封装解决方案。这个解决方案将源极连接分为两个电流路径；一个用于实现功率连接，另一个用于实现驱动器连接。这样一来，器件就能保持快的开关速度，同时又不必牺牲接通和关断控制能力。

CRMICRO功率器件在不间断电源（UPS）上的应用

目前变换电路频率的提高，使得用于滤波的电感、电容以及噪音、体积等大为减少，使UPS效率、动态响应特性和控制精度等大为提高；因此适用高频应用，且低功耗、可靠性强的电力电子开关器件将成为UPS未来核心需求。以在线式UPS为例，PFC部分应用HV-MOS/IGBT+FRD/SiC JBS；DC-DC部分应用LV-MOS；DC-AC部分应用IGBT。

如何为开关电源电路选择合适的元器件和参数

很多的未使用过开关电源设计的工程师会对它产生一定的畏惧心理，比如担心开关电源的干扰问题、PCB layout问题、元器件的参数和类型选择问题等。其实只要了解了，使用一个开关电源设计还是非常方便的。一个开关电源一般包含有开关电源控制器和输出两部分，有些控制器会将MOSFET集成到芯片中去，这样使用就更简单了，还简化了PCB设计，但是设计的灵活性就减少了一些。开关控制器基本上就是一个闭环的反馈控制系统，一般都会有一个反馈输出电压的采样电路以及反馈环的控制电路。因此这部分的设计在于保证精确的采样电路、控制反馈深度，因为如果反馈环响应过慢的话，对瞬态响应能力是会有很多影响的。而输出部分设计包含了输出电容、输出电感以及MOSFET等等，这些元件的选择基本上要满足一个性能和成本的平衡：高的开关频率就可以使用小的电感值(意味着小的封装和便宜的成本)，但是较高的开关频率会增加干扰和增大MOSFET的开关损耗，使效率降低;低的开关频率带来的结果则恰好相反。对于输出电容的ESR和MOSFET的Rds_on参数选择也是非常关键的：选择小的ESR可以减小输出纹波，但是电容成本就会增加(好的电容会贵嘛)。开关电源控制器驱动能力也是需要注意：过多的MOSFET是不能被很好驱动的。一般来说，开关电源控制器的供应商会提供具体的计算公式和使用方案供工程师借鉴。
