bidirectional switch meaning in Chinese

双向接线器
双向开关
双向转换开关

In this dissertation , a novel bidirectional dc / dc converter ' s topology was designed , witch used in vehicle power supply systems . the converter is composed of fundamental bidirectional switch cell , using phase - shifted full - bridge zvs pwm dc / dc converter in buck circuit and using push - pull boost converter in boost circuit
文中从双向dc dc变换基本单元入手，针对某大型车载电源系统设计了一种新型双向dc dc变换器拓扑电路，降压变换采用移相全桥式zvs ? pwm功率变换，升压变换采用推挽式dc dcboost功率变换。
In this strategy , an mc is first transformed into an equivalent topology resulting from the combination of a rectifier and an inverter , then , the dtc and the current space vector modulation are respectively performed on the inverter and the rectifier sides , and the strategies on the two sides are finally synthesized and changed into the control signals of the nine bidirectional switches in mc
该策略先将矩阵式变换器等效成整流器和逆变器的组合，然后在逆变侧进行直接转矩控制，在整流侧进行电流空间矢量调制，最后将两侧的策略进行综合，并转化成矩阵式变换器9个开关的控制信号。
