Abstract:
     The filter network and module of filter network are setup between power input end and rectification circuit. The filter network includes seven capacitors; internal connecting ends of capacitors are connected to each other, and external connecting ends of capacitors constitute passive linear network in seven ends. An external connecting end of one capacitor is connected to ground of power source. Other six capacitors are paired to three groups, and parameters in each capacitor group are identical. External connecting ends of first group as input ends are connected to two input ends of power source. External connecting ends of second group as middle ends are connected to two input ends of rectification circuit. External connecting ends of third group as output ends are connected to two output ends of rectification circuit. The module is encapsulated as thick film IC with nine pins. Features are simple, compact, stable for solving electromagnetic interference.
