查询词典 luminous flux

Quasi-constant torque control is used when the speed is lower than 125 km/h, and constant power control is applied when the speed is higher than 125 km/h. Direct rotor flux oriented control system is employed and three-level neutral point clamped traction inverter with SVPWM control is adopted.

在速度低于125km/h采用准恒转矩控制，速度高于125km/h采用恒功率控制，采用直接转子磁场定向控制系统，牵引逆变器采用空间电压矢量控制的带中点钳位二极管的三电平拓扑结构。

But due to significant magnetic flux leakage present in the loosely wound embedded solenoid inductor structure, large inductance cannot be realized in a compact structure. This is followed by the design of a LTCC common-mode filter intended for use with USB 2.0 products. As compared to the wire-wound common-mode choke, the designed multi-layer common-mode filter produces lower insertion loss on differential-mode signal than conventional ferrite-based common-mode filter.
