整流桥模块690伏交流电1 600模数转换器空气冷却的受保护的预充电电路整流桥模块的整流作用是利用极管的单向导通原理来实现的。通常而言，二极管是正向导通反方向截止，即二极管只容许其正极进到正电，负极进到负电。整流桥模块的极管只容许电流在一个方向利用，所以当它接入到交流线路时，它可以使电路中的电流只向1个方向流动。整流桥模块通常由单相桥式全波整流器的4个二_极管构成和三相桥式全波整流器的6个极管构成生产厂 家都将其封装在一个元器件中，通称为整流桥模块，便于我们使用。对应用作单相电路和三相电路整流。关于单相全波整流桥，在整流桥模块的每一个工作周期中, 唯有2个二极管一起运行，二极管的单向导通作用将交流电转变为单向直流脉动电压。整流桥模块的一个极管的最大耐压是输出电压的倍,利用的电流是输出电流的一半。因为每一个周期唯有2个二 极管运行，即每一个极管只运行半个周期，所以唯有一半的电流利用。 对于电压，当极管反方向偏置时，要承担滤波电容和输入端电压之和，为输出电压的二倍。这在选择整流桥模块时极其重要。

The rectifier bridge module is a protected pre charging circuit for air cooling of a 690V AC 1600 analog-to-digital converter. The rectifier function of the rectifier bridge module is achieved using the principle of unidirectional conduction of the transistor. Generally speaking, diodes conduct in the forward direction and cut off in the opposite direction, meaning that the diode only allows its positive electrode to charge positively and its negative electrode to charge negatively. The transistor of the rectifier bridge module only allows current to be utilized in one direction, so when it is connected to an AC line, it can make the current in the circuit flow only in one direction. The rectifier bridge module is usually composed of four diodes of a single-phase bridge full wave rectifier_ The manufacturers of the six transistor components of the transistor composition and three-phase bridge full wave rectifier package them in one component, commonly known as the rectifier bridge module, for our convenience in use. Apply for single-phase and three-phase circuit rectification. Regarding single-phase full wave rectifier bridges, in each working cycle of the rectifier bridge module, only two diodes operate together, and the unidirectional conduction effect of the diodes converts AC power into unidirectional DC pulsating voltage. The maximum withstand voltage of one transistor in the rectifier bridge module is twice the output voltage, and the current utilized is half of the output current. Because only 2 diodes operate in each cycle, meaning each transistor only runs for half a cycle, only half of the current is utilized. For voltage, when the transistor is biased in the opposite direction, it must bear the sum of the filtering capacitor and the input voltage, which is twice the output voltage. This is extremely important when selecting the rectifier bridge module.
