Switch mode power supplies and DC/DC switching controllers are state of the art and allow great efficiency, but if the design of the circuit and circuit board layout is less than ideal this can result in increased emission of radio interference voltage. This article discusses the systematic ...
2. FSO461 has filter circuitry only. To be used with DSF500 for conducted immunity compliance. 3. DSF500 has surge protection only. To meet stated EMC performance it must be used with FSO461. 4. For models without overtemperature protection, add suffix ‘-H’ e.g. DSF500-H. ...
There are several damping strategies to consider—first, a simplified series-damped filter circuit with a resistor in parallel with the inductor. The damping at the corner frequency is much better, but it comes at the cost of decreased high-frequency attenuation due to the addition of a zero ...
Fig.6 Design flow of the hybrid EMI filter 通过计算EMI滤波器参数,使加入EMI滤波器后同步Buck DC-DC变换器符合EMC标准要求。为了确定EMI滤波器组件的参数值,需要将ILReq与所计算的插入损耗ILcalc进行比较,在符合EMC标准的要求情况下(包括CM和DM电磁干扰),计算EMI滤波器组件参数,使ILReq和ILcalc的二次方均值在...
