概述

脉冲变压器是一种利用磁饱和特性进行能量转换的器件，广泛应用于开关电源、逆变器、变频器等电力电子装置中。

工作原理

脉冲变压器的工作原理基于磁饱和特性。当施加在脉冲变压器原边绕组的电压超过其磁芯的饱和磁感应强度时，磁芯将进入饱和状态。在饱和状态下，磁芯的磁导率急剧下降，从而导致原边绕组的电流迅速增加。这种电流变化会在变压器的次级绕组中感应出相应的脉冲电压。

summarize

Pulse transformer is a kind of energy conversion device using magnetic saturation characteristics, which is widely used in power electronic devices such as switching power supply, inverter and frequency converter.

Working principle

The working principle of the pulse transformer is based on the magnetic saturation characteristics. When the voltage applied to the primary winding of the pulse transformer exceeds the saturation magnetic induction intensity of the magnetic core, the magnetic core will enter the saturation state. In the saturated state, the permeability of the magnetic core decreases sharply, resulting in a rapid increase in the current of the primary side winding. This current change induces a corresponding pulse voltage in the secondary winding of the transformer.
