crystal switch meaning in Chinese

晶体开关

In all kinds of switches , thermo - optical switch , mems switch , liquid - crystal switch and air bladder switch are the trend of large - scale switch array , and lithium niobate electro - optical switches and electro - optical polymer switches are the trend of fast switches
在各种光开关中，热光开关列阵、微机械光开关列阵、液晶光开关以及气泡式光开关列阵由于集成度较大，因而将是大规模阵列光开关的发展方向。
The electric power harmonic comprehensive control system with low cast and high security is applied in this article . it adopts that sourced compensation links with non - sourced compensation herewhich the former is realized by high frequency pwm control technology and the latter is carried out by crystal switch formed by non - flow and over - voltage . it can realize stepless modulation with imaginary power , mightiness compensation of harmonic and negative electricity , and circuitry consumption debasing are achieved
提出采用有源补偿与无源补偿相结合的电力谐波综合治理技术及装置，无源部分采用无涌流和过电压的晶闸管控制电容器技术实现，有源部分采用高频pwm控制技术实现，成本低、可靠性高、可实现无功功率的无级调节、强力补偿谐波电流和负序电流，降低线路损耗。
