单向磁化 meaning in English
unidirectional magnetization
Examples
- 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。 - In order to increase the utilization of transformer core and reduce the number of transformers , the two - transisteor integrated - magnetics forward converter is studied in this paper . the phenomena about magnetic deviation due to asynchronism of duty cycle and other parameters is analyed , and the converter works normally although there is magnetic deviation . the working principle of circling current is analyed , and a improving circuit is present to decrease the circling current
分析了双管正激磁集成变换器的环流产生机理，提出了一种减小环流的方法；研究了占空比等参数不一致导致的磁芯偏磁问题，磁芯存在单向磁化现象，但不会出现单向磁饱和，变换器仍能稳定工作。
