直流输电系统能够长时间持续运行，需要一颗强大而又稳定的心脏，那就是整个直流工程最关键的设备——换流器，我们也称之为换流阀。今天，我们来一起探讨换流器的基本工作原理。

首先，换流器的功能是：实现ac-dc或者dc-ac的变换，前者称为整流，后者称为逆变。这是最基本，也是直流输电系统最核心的功能。

为了实现这个功能，一定的物理结构是必须的，也就是我们所说的结线方式。结线方式是多种多样的，其中三相桥式结线最为常用，由6个桥臂组成，每一个桥臂由数十个至数百个串联的晶闸管元件组成。桥臂具有阀的特性，正常情况下只能从阳极到阴极单方向导通。

Dc power transmission system can run for a long time, need a strong and stable heart, that is the most critical equipment of the entire DC project - converter, we also call the converter valve. Today, we will discuss the basic working principle of the converter.

First of all, the function of the converter is: to achieve ac-dc or dc-ac transformation, the former is called rectification, the latter is called inverter. This is the most basic, but also the most core function of the HVDC system.

In order to achieve this function, a certain physical structure is required, which is what we call the wiring method. There are a variety of wiring methods, of which three-phase bridge wiring is the most commonly used, consisting of six bridge arms, each of which is composed of dozens to hundreds of thyristor elements in series. The bridge arm has the characteristics of a valve, and under normal circumstances can only be one-way from the anode to the cathode.
