并联逆变器的含义，电流顺时针流动

并联逆变器由两个晶闸管(T1和T2)、一个电容器、中心抽头变压器和一个电感器组成。晶闸管用于提供电流通路，而电感器L用于使电流源恒定。这些晶闸管由连接在它们之间的换向电容器控制导通和关断。并联逆变器是什么意思这互补换向方法用于打开和关闭电容器。互补换向意味着当T1接通时，点火角被施加到T2，然后电容器将关断T1。确切的情况是，当T2开启且点火角施加到T1时，由于电容电压，T2将关闭。输出...[详细]
新能源汽车的不稳定因素目前都有哪些

随着汽车的逐渐增多，环境压力也逐渐变得越来越大。也是这个时候，有人说新能源汽车节能环保，和传统用油的汽车有很大不同，这着实吸引了一大批受众。那么新能源到底能不能买呢？这个问题其实是非常困扰消费者的。如果你在北上广一线城市的话，新能源汽车是没有什么大问题的。毕竟现在的大环境下，大城市还是非常主要节能的，而新能源车牌也确实是一个非常有诱惑力的标签。但如果你所在的城市限行，上牌不需要摇号等，还是...[详细]
对于纯电动汽车它是否是真的环保

近几年来，很多人都换上了新能源汽车，而这种车也确实受到了大力的追捧，也认为是未来汽车发展的方向，甚至将来会彻底地取代燃油车。但这些不过都是大家看到的表面现象，而事实上的新能源存在的问题还很多，之所以有这么多人选择了这种车，无非就是看上了国家补贴的政策，也就是说没有了这个补贴，或许这种车型也不会有如此快速的发展，但很多人都在怀疑，相比燃油车，这种车真的环保吗？电动汽车发展到现在也有百年的历史...[详细]

伺服电机和步进电机的区别

伺服电机又称执行电机，在自动控制系统中，用作执行元件，把收到的电信号转换成电机轴上的角位移或角速度输出。伺服电机内部的转子是永磁铁，驱动器控制的U/V/W三相电形成电磁场，转子在此磁场的作用下转动，同时电机自带的编码器反馈信号给驱动器，驱动器根据反馈值与目标值进行比较，调整转子转动的角度。伺服电机的精度决定于编码器的精度（线数）也就是说伺服电机本身具备发出脉冲的功能，它每旋转一个角度，都会发出对...[详细]
变频器与继电器的功能选择

1、变频电机停止，发热源没了，散热原件自身辐射、热传导功能足以保证变频器温度不继续升高。 2、即使变频器温度继续升高，升高的幅度也不大，对电源模块没有什么影响。变频器只要在电源输入R、S、T和输出U、V、W线路上接好线即可，内部的散热保护风扇都是变频器，接通电源后会一直处于工作状态，包括变频器内部的软启软停、过载保护、过热保护、过压保护、过流保护、掉载保护、欠压保护、短路保护、缺相保护、接地保...[详细]
