Cascaded multilevel inverters which is controlled by triangular carrier phase shift technique is in the leading role of high voltage and high power AC variable frequency speed regulating. 在高压大功率交流变频调速领域,级联式多电平逆变器目前处于主导地位,而三角载波移相控制技术又是其较适合的控制方略。
The modal control is analysed in cases of all modal controlled and limited modal controlled respectively. The time delay is compensated using method of phase shift. 模态控制分控制全部模态和控制有限模态两种情况,时滞补偿采用移相补偿。
An integrated LC Voltage Controlled Oscillator ( VCO ) using enhanced resonator has been implemented in a PLL ( Phase Locked Loop ) for an ASK ( Amplitude Shift Key ) Receiver IC chip. 本文介绍了一种适用于ASK幅移键控接收器芯片中锁相环电路,集成于芯片内的LC压控振荡器,它的LC振荡电路采用了一种增强型的特别结构。
