<p>PURPOSE:To be ready for coping with a sudden fluctuation of synchronizing power input by inserting and connecting a damping resistance to suppress a transient phenomenon at the time of sudden fluctuation of a filter input voltage to LC resonance circuit. CONSTITUTION:A series circuit coming in an inductance L1 and condensers C1, C2 is connected to an input terminal, both ends of the condenser C2 are led to an output terminal through an inductance L2, and resistances R1, R2 are inserted and so connected. That the resistance is divided into R1 and R2 is serviceable for correction of a deviation of an output phase due to insertion of a damping resistance. The greater the damping resistance value is, the larger a transient phenomenon suppression effect becomes, however, simply increasing the value is not for obtaining the effect of a filter, therefore a nearest possible value to keep low-frequency oscillation within a permissible value is selected.</p> |
