随着电气设备应用的日益宽泛,电子设备产生的电磁噪声也越来越严重,干扰了电子设备的正常工作,特别是对一些低功耗的便携式设备更是如此。电源滤波器最基本的作用就是抑制传导干扰,有的品种也能提高对副射干扰的抑制能力。
军工电源是将其它形式的能转换成电能的装置。自“磁生电”原理,由水力、风力、海潮、水坝水压差、太阳能等可再生能源,及烧煤炭、油渣等产生电力来源。军工电源部件需要做的安规检查有哪些呢?看国创小编总结!
滤波器是由电容、电感和电阻组成的滤波电路。是一种选频装置,可以使信号中特定的频率成分通过,而极大地衰减其它频率成分。看国创总结滤波器根据选频作用的分类!
肖特基二极管不是利用p型半导体与n型半导体接触形成pn结原理制作的,而是利用金属与半导体接触形成的金属-半导体结原理制作的。它是一种热载流子二极管。不同类型的二极管有不同的特性参数。看国创总结肖特基二极管的主要参数!
低频纹波是与输出电路的滤波电容容量相关。由于军工电源体积的限制,电解电容的容量不可能无限制地增加,导致输出低频纹波的残留,该输出纹波频率随整流电路方式的不同而不同。
