switch turn造句
例句与造句
- once you have the switches turned on, you can look at the available data . to look at a snapshot, you use the
一旦打开了开关，便可以查看已经提供的数据。要查看一个快照，可以使用 - the auxiliary switch conducts when the two main switch turn off, and it also operates at zcs conditions . this switch not only helps the main switches achieve zvs, furthermore, it eliminates the oscillation between the transformer leakage inductance and the junction capacitance of two switches
辅助开关管为主开关管实现zvs创造了条件,同时辅助开关管在主开关管关闭期间实现zcs导通,大大减轻了变压器漏感和主开关管结电容之间的振荡。 - what have made a large amount of harmonic and high electro-magnetic interference ( emi ) has two reasons . the first reason is mainly the hard-switching pwm mode . the switch turns on at high voltage and turns off at high current in a short time ( ns ), which leads to a high du / dt and di / dt and emi
其原因一是由于硬开关的pwm调节方式，电子开关速度很快(ns数量级)在高电压下导通，大电流下关断，导致很高的dudt和didt，产生很强的尖峰脉冲，对周围环境造成电磁干扰。 - the second, at the high frequency primary coil, when switch turn on with control signal ( the spwm pulse is modulated ), in the positive or negative semi-period of low frequency modulation signal, transformer coil with same direction voltage . the magnetic flux of transformer core will increase step by step . at the end, it leads to magnetic flux saturation
二、在高频变压器原边，当开关管接收控制信号脉冲列(经调制的spwm波列)导通时，在低频调制信号的正半周或负半周内，施加在变压器绕组上的是同一方向的电压，变压器磁芯中的磁通可能将级进地逐渐增加，导致磁芯饱和，造成磁偏或单向磁化，导致低频电信号放大失真或由于很大的磁化电流而无法正常工作。 - It's difficult to find switch turn in a sentence. 用switch turn造句挺难的
