背景

耦合是两个或多个电路元件的输入和输出相互影响，能量从一端传递到另一端的现象。当线圈通过交流电时，线圈周围会产生感应磁场。如果两个线圈相互作用，则称它们是磁耦合的。两个或多个具有磁耦合的线圈称为耦合线圈，即耦合电感。
耦合电感常见的电路拓扑是SEPIC拓扑，SEPIC是单端初级电感转换器。该拓扑最大的优点是输入输出同极性，适用于电池供电的应用场景，如LED照明等。在SEPIC电路中，常使用耦合电感来实现电路功能。与两个单电感器相比，耦合电感器减少了元件数量，提高了集成度，提高了效率，并提供了更好的环路控制特性和更少的 EMI 挑战。

Background

Coupling is the phenomenon in which the input and output of two or more circuit components affect

each other and energy is transferred from one end to the other. When a coil passes through an alternating current, an induced magnetic field is generated around the coil. If the two coils interact with each other, they are said to be magnetically coupled. Two or more coils with magnetic coupling are called coupling coils, that is, coupling inductor.

The common circuit topology of coupled inductor is SEPIC topology, SEPIC is Single Ended Primary

Inductance Converter. The biggest advantage of the topology is that the input and output are

homopolarity, which is suitable for battery-powered application scenarios, such as LED lighting, etc. In

SEPIC circuits, coupling inductors are often used to realize circuit functions. Compared to two single

inductors, coupled inductors reduce the number of components, improve integration, improve efficiency, and provide better characteristics of loop control and fewer EMI challenges.
