forward voltage drop造句

• Forward voltage drop
  正向电压降
• The forward voltage drop in the on - state is only a few volts ( typically 1 to 3 v depending on the device blocking voltage rating )
  在导通状态的正向压降很小（取决于阻断电压的值，一般为1 ~ 3伏） 。
• Specific issues examined are : compensation for the variation of the stator resistance , the offset error of the dc bus voltage , the voltage error generated by the forward voltage drop the dead time of the switches , improvement of the steady state performance , and the speed sensorless control for the pmsm dtc drive system are of major concern in this thesis
  定子电阻变化，直流母线电压漂移，开关器件反向相电压降、逆变器死区时间引起的电压误差的补偿，提高系统稳态运行性能以及永磁同步电机直接转矩控制的无速度传感器运行方案等问题都是本文研究的重点。转矩的快速响应是直接转矩控制算法的一个卓越的性能。
• Unfortunately , though the lifetime control technology reduces the stored charge , it increases the forward voltage drop ( vr ) and the reverse leakage current ( i , ) . therefore , si pin diode cannot realize a good trade - off in qs - vf - i , - . the appearance of sige material and sige / si hetero - junction technology has changed this situation
  但少子寿命控制技术在减少存贮电贺q _ s的同时，也增大了正向通态压降v _ f ，和反向漏电流i _ r ，因此很难实现qs - v _ f - i _ r三者良好的折衷关系。
