可控整流中晶闸管参数的选择及其应用

晶闸管的选择参数很多，但用于可控整流时，主要是额定电流、额定电压的计算与选择。晶闸管由于过电流过电压能力低，文常常工作在不同的电流波形情况下，给额定电流的选择带来一定的困难，如若额定值选择不当，会造成不必要的损失或浪费。根据实际工作条件，在满足需要的前提下，应尽量降低晶闸管的定额，以减少设备投资。

Transistor Selecting Method and Its Application of Controlled Rectification

We have a lot of parameters to choose transistor, but when we use it in controlled rectification, the specified electric current and the specified voltage are the principal ones. Transistor has low ability of carrying electric current and voltage, and it often works in different forms of wave, so we have a certain difficulty in choosing it. If specified value is chosen improperly, unnecessary loss or waste will be caused. According to the actual condition of work and on the premise of meeting the need, we should try our best to reduce the specified value of the transistor in order to reduce equipment investment.
