IGBTs的音标

To reduce the switching losses of IGBTs in PWM rectifier, a third order square wave is added to the phase voltage control signal on the basis of the Improved Period Average Model. This new control algorithm leads to no switching in about 1/ 3 cycle.

为降低PWM整流器的开关频率，本文在整流器的改进周期平均模型基础上，在相电压控制信号中叠加三次方波信号，使得整流器中的开关管有1／3时间不动作。

The prototype of UPFC ( unified power flow controller) is realized by using two identical back to back converters, in which the switch components are IPMs ( intelligent power modules) consisting of IGBTs ( insulated gate bipolar thyristors).

文中用两个统一格式的背靠背逆变器实现了统一潮流控制器物理模型，开关元件采用绝缘栅双极型晶闸管构成的智能功率模块。

Because There is a relationship between the loop of conducted interference and turn-on and turn-off of the up and down bridge arm IGBTs, analyze the loop of CM interference and DM interference as the state of IGBT.

由于传导干扰的路径和上下桥臂IGBT的开通和关断有很大关系，因此分析了IGBT不同的开关状态下的共模干扰和差模干扰的传播路径及其共模干扰和差模干扰传播的特点。
