电容在电流滤波中扮演的角色与设计选型技巧
发布日期:2026-10-26
电容在电流滤波过程中扮演储能与抑制噪声的关键角色,是电源电路与信号处理中不可或缺的器件之一。电容在电流滤波中的主要功能包括电源平滑、旁路、去耦、滤波、瞬态补偿等功能,通过合理选型与布局设计,电容能有效抑制电流脉动、减少电磁干扰、提升系统稳定性,是所有电源与信号电路中维持“干净电流”的核心器件。
常见的负电压应用场景与设计注意事项
发布日期:2026-10-23
电压是电路中两个点之间的电位差,通常我们会选择某个点作为参考点(通常是地GND),并以此来定义其他电位的高低。当一个电路节点的电位低于参考点(地)时,所测得的电压值就是负电压。也就是说,负电压并不是“不存在的电压”,而是相对于参考点更低的电位。

电流倒灌的保护方案与设计上的注意事项
发布日期:2026-07-24
电流倒灌是指电流从负载端或其他电路节点反向流入电源或前级电路的现象。换句话说,本来电流应该是由电源流向负载,但在某些情况下,路径被反转,导致电流“回灌”到来源端,这就是电流倒灌。电流倒灌多半发生在“多电源并存”、“电源时序错乱”或“电感元器件释放能量”的情况下。
