PURPOSE:To prevent a vibration phenomenon occurred in a DC filter by providing in parallel a controllable rectifying element to be controlled for its conduction and a resistor with a series circuit of a power source side switching means and a reactor during a normal operation. CONSTITUTION:A main...
Application Report SNVA801 – November 2017 Analysis and Design of Input Filter for DC-DC Circuit Charles Zhang ABSTRACT When designing DC-DC circuits, it is common to add the input filter circuit before the power stage. An LC filter is one of most frequently used input filter circuit. ...

目前小型化的无线传感器网络节点的供电单元普遍采用AA电池与升压型DC/DC组成的供电系统为节点供电,如克尔斯博(Crossbow)公司推出的Mica系列节点[4-5]。由于升压型DC/DC能在电池的输出电压低于系统工作电压后还能将电压提升供节点使用一段时间,这样可使得电池电量得到更为充分的利用。本文基于ZigBee技术研制了一种无线传感...

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 in the filter’s frequency response....
