    就是步进电机其中的一个重要参数,步距角。细致来说,当步进电机接收到一个电脉冲信号后,A相通电,A方向的磁通经转子形成闭合回路。若转子和磁场轴线方向原有一定角度,则在磁场的作用下,转子被磁化,吸引转子,使转、定子的齿对齐停止转动。即A相通电使转子3齿和AA'对齐;下一个脉冲信号来,B相通电使转子4齿和BB'对齐;第三个脉冲信号来后,C相通电使转子1齿和CC'对齐。这种驱动方式即为三相三拍驱动方式。如下图:所以,步进电机是靠脉冲数量来转动的,需要转多少圈就给相应个数的脉冲数。因此,步进电机能够达到准确定位的目的;同时可以通过控制脉冲频率来控制电机转动的速度和加速度,也就是控制多长时间给一个脉冲。从而达到调速的目。

    ZVS),或是通过开关管的电流为零,即零电流开关(Zero-Current·Switching,ZCS)。这种软开关方式可以显着地减小开关损耗,以及开关过程中激起的振荡,使开关频率可以大幅度提高,为转换器的小型化和模块化创造了条件。功率场效应管(MOSFET)是应用较多的开关器件,它有较高的开关速度,但同时也有较大的寄生电容。它关断时,在外电压的作用下,其寄生电容充满电,如果在其开通前不将这一部分电荷放掉,则将消耗于器件内部,这就是容性开通损耗。为了减小或消除这种损耗,功率场效应管宜采用零电压开通方式(ZVS)。绝缘栅双极性晶体管(InsulatedGateBipolartansistor,IGBT)是一种复合开关器。

    所以体积和重量只有线性电源的20~30%。功耗小、效率高:功率晶体管工作在开关状态,所以晶体管上的功耗小,转化效率高,一般为60~70%,而线性电电源只有30~40%。[1]工作模式编辑顾名思义,开关电源就是利用电子开关器件(如晶体管、场效应管、可控硅闸流管等),开关电源及电路图开关电源及电路图通过控制电路,使电子开关器件不停地“接通”和“关断”,让电子开关器件对输入电压进行脉冲调制,从而实现DC/AC、DC/DC电压变换,以及输出电压可调和自动稳压。开关电源一般有三种工作模式:频率、脉冲宽度固定模式,频率固定、脉冲宽度可变模式,频率、脉冲宽度可变模式。前一种工作模式多用于DC/AC逆变电源。或DC/DC电压变。FINE POWEREX电源FES30-12欢迎来电查询
