此外,适当增加电感量,可改善低频衰减特性。C1和C2采用薄膜电容器,容量范围大致是0.01Μf~0.47μF,主要用来滤除串模干扰。C3和C4跨接在输出端,并将电容器的中点接地,能有效地抑制共模干扰。C3和C4亦可并联在输入端,仍选用陶瓷电容,容量范围是2200Pf~0.1μF。为减小漏电流,电容量不得超过0.1μF,并且电容器中点应...
Radio interference suppression filters must be used in order to conform to limit value class A1. Additional loads must be connected upstream of the filter (line side). The control used and the manner in which the rest of the control cabinet is wired will determine whether an additional line ...
Additional loads must be connected upstream of the filter (line side). The control used and the manner in which the rest of the control cabinet is wired will determine whether an additional line filter needs to be installed. Rule 13 A commutating reactor must be included in the field ...

以往我们最常看到谈EMI对策离不开屏蔽(Shielding),滤波(Filter),接地(Grounding)对于接地往往一块电路板多已固定而无法再做处理因为这一部份在电路板布线(Layout)时就须仔细考虑若板子已完成则此时可变动的空间就非常小一般方式仅能找出噪声小的接地处用较粗的地线连接减低共模(Common mode 8、)噪声。屏蔽所牵涉的...

filter must be much less than the input impedance of the converter. This can be achieved with an extra damping circuit R and C5 in Figure 3. C5 is >>5 x C2, which may be internal to the DC-DC and R is = SQRT(L/C2). Alternatively, a lossy electrolytic capacitor has a similar ...
